Yes we do help our clients in the installation issues. Moreover we can also do installation on server for you at no extra cost.

You will receive a download link in the email when your payment is verified by our authorized retailer (such as Plimus.com, Avangate.com)
The filesize is approximately 4.5MB

You will have access to the fully functional live demo on our servers.
You can access the admin section, merchant section, visitor section and public section.
You can test the product for as long as you like with no limitations.

Yes we do offer customization services to the scripts at an extra cost. Charges depend upon the time and efforts required to perform those customizations.

Our price comparison script can be used in both manners.

• Running it as a service where you charge registered shop-owners (merchants) flat monthly/yearly fee for their listings (as well as you can also charge them per clickthroughs - this is all configurable in admin panel).
  
  
• Running it as an affiliate site where you add shop-owners (merchants), upload their datafeeds and you get paid on each sale made at their website.
  You have every tool available in the admin panel to add shop-owners, upload their datafeeds and manage everything else. Just remove link to the merchant area on your homepage by editing footer.php file (example of Affiliate Site : www.pricemags.com).

This is just another negative marketing campaign from our competitors.

All public pages, template files, common includes, merchant visual pages are open source.
You can easily edit them. You can easily edit template files (provided you know HTML, CSS and web-designing). You can easily change other visual aspects. You can even easily add new fields to the products, merchants, categories, prices tables.
There are many sites which clients edited themselves and are now very unique and great looking.

Only admin panel and some includes are encrypted to implement licensing and avoid misuse.

Anyone who claims that all files are encrypted has not actually received our script legally and is just making false claim.
Our versions before 2006 where not even encrypted with ioncube and thus were widely distributed. We have seen alot of misuse and distribution in recent years and had to take some preventive measures.

The script can adapt itself to the hosting environment and the restrictions in effect.
The default script comes with configuration to use low memory thus is slow on import.
On a shared server the script import products one by one in a sequential manner which can make import slow. However script support faster methods but they wont work on shared environment due to the fact that shared server is highly restricted.

On VPS/semi-dedicated machines where you have more previliges there you can enable multi-tasking import process which is atleast 5 times faster than the convential sequential manner.

If config file is adjusted, it can import 300,000 products in just 4 minutes. I will paste the small clip of log below (test done with multi-tasking enabled on a dedicated P4, 1GB server):

[2008-03-29 17:50:21] ---- Total Rows in file are 392040
[2008-03-29 17:50:26] ------ Log of actions will be created here.
[2008-03-29 17:54:51] ------ FEED file processed. Lines:392039, Success: 392036, Failure:3, NotFound:0, Msg: Datafeed file processed.

The default script comes with very basic configuration so that it can work on any hosting environment.
The default search can become slow once your system grows with number of products. However our script supports different search options to increase the speed. You can enable FULL TEXT search supported by MYSQL. If you are on VPS/dedicated machine and have sphinx installed then you can even enable sphinx search. Sphinx search is the ultimate in searching with acuracy and speed.

I searched nokia on www.24vergelijk.nl and got 2,474 results in just 0.1 seconds. They have a inventory of 2,132,279 products and are running website on VPS.

Price comparison script can work on low resources as well as may require high resources. It depends upon what you want to achieve. If you want to start a niche specific website with few thousand products then you dont need much resources and shared hosting will work for you. BUT if you want to run a price comparison website with few million products than obviously you need resources and a server for that.

Your server should reflect the amount of items/offers you wish to display on your website and store in your database.

Common sense rule:
Even in day to day life, if you want to move horse from one city to another you wont try to put it in a 800cc saloon car. Instead you will need a vehicle suitable for that purpose. The same common sense applies here. You need a server with resources matching the number of products you plan to store.
We get buyers who put 600,000+ products on a tiny shared server and then curse us that the script is not working fast.

This is just another example of false marketing against us. I guess our competitors spend more time making false statments on forums then they work on improving their software.

To answer the question, this script has been tested on CJ feeds. Not just tested, CJ feeds are used regularly by our clients to update their products and prices.

We even have a separate section in autofeed addon where you can configure the CJ bundled zip file. CJ now give a single zip file of several merchant datafeeds zipped together.
Further we also have CJ XML API utility where you can use CJ XML API to import products from your joined merchants (advertiser) of CJ affiliate network.

One thing to note is that CJ bundled file is usually very large in filesize of over 500MB (sometimes over 1.5GB) in zip. Here the common sense rule applies as mentioned in previous answer. On shared server you are not even allowed to download a file of such size, even most of the time your FTP connection is restricted to 30 seconds.
Further once a file is downloaded on shared server (on some US hosts clients are successful in downloading upto 1.3GB files) then you need to unzip it. By default our script uses php native code to unzip a zipped file but php cannot unzip a 500MB zip file (php maximum memory limitations on a default server is 128MB) and for 500MB file php need to execute shell command to unzip this large file. Again on shared hosting server you are not allowed to run shell commands so you cannot move ahead.

Please plan your work, plan what is the file size from CJ and are you able to download and unzip it within default settings of your hosts or you need some custom previliges only available in VPS/dedicated machines.
Feel free to contact us if you are in doubt. Tell us what you want to accomplish.

Another false accusation put to rest.

Payments can be made by :
- Credit/Debit Card (Visa, Mastercard, American Express, Discover, JCB, Diners)
- Digital Check (US Bank Account Required)

A merchant will get this message when he has no active package registered to him. When you register a merchant, his payment for the package must be verified (approved) by the administrator.
In order to approve the payment for the package, please log into the administrator section and from the Navigation Menu on left goto Current Merchants. This will display the list of merchants registered on your system. Against your desired merchant click on the package payment icon (it is second $ icon from left).
After clicking another page will open showing the list of payments made by that merchant. Please activate the payment made by that merchant by clicking on the red arrow icon. This will activate his package payment and now merchant can log into his area will all previliges.

You can get a detailed help on crawlers by going to this link.
products.kaonsoftwares.com/price-comparison-help/admin-manage-product-crawler.php
products.kaonsoftwares.com/price-comparison-help/admin-manage-price-crawler.php

Product crawler is only used to extract product information from the merchant`s website. It extracts product name, its description and its image from the website. However price crawler only update prices for products.

New product insertion is not required at regular basis however price updating is. For that reason both crawlers are separate so that they can run at different intervals. Secondly it is also done to keep crawlers comparatively light weight (crawling is very resource hungry and takes of time to finish).

Please visit our step by step tutorial for help on importing datafeeds.
http://products.kaonsoftwares.com/price-comparison-help/admin-import-products.php

CSV and Feeds import is very flexible and is not bound to any format. You can upload many various of formats. Please see following page to understand more about it.
http://products.kaonsoftwares.com/price-comparison-help/admin-import-products.php

Sample XML format is at following link.
upload/xmlfiles/sample_user_products.xml
It is just a sample format. You can also import other different format XML files. You can import variety of file formats by just specifing the XML tags that map to the product columns. This way correct data is imported into the system. 

Please go to following link for manual.
products.kaonsoftwares.com/price-comparison-help/

Please browse to <script-root>/include/ and then open constants.php in your favorite text editor. Then go to line number 32.

It will look like following image:


Now edit this line (line number 32) and change N to Y. Edit the line $USE_MOD_REWRITE = 'N' to $USE_MOD_REWRITE = 'Y'

After editing it will look like following


Save and upload again to your server. Now it will be using search engine friendly urls. Now import datafeed or add categories/products and they will all have search engine friendly urls.

Note: If you already had products in your database and you have enabled search engine friendly urls then you will "Invalid Product URL" error on your website. To overcome this either again add products OR use Rebuild Search engine friendly URLs in your admin toolkit section.
