Product Price Comparison (PPC)

Example : Get HTML Code Wizard
Related docs: PPC Documentation | What is DFF Product SKU? | What is the difference between DFF SKU, Merchant SKU and PrdtID?

There are two types of Product Price Comparison (PPC) script.

Standalone PPC
First is the standalone PPC which is called directly using the following calling line (example of standalone PPC):

<script language="javascript" src=""></script>


Note: there is also PPC version 2, which outputs HTML with CSS elements DIVs and SPANs allowing you to have full control on its styling.

PPC Extended from PSE
The second type of PPC is one that extends from PSE, PSE is the price search engine, if you click 'Compare # Price' from PSE it will automatically display PPC script without any additional calling of DFF script. This PPC which extends PSE automatically inherit the options, parameters and styling from the parent PSE.

Available Options of Standalone PPC Script

How to control Design, Color and Style?
If you are using Javascript output or HTML output via any of the dynamic web scripting language you can control the styling of the search result output in several ways.
  1. The easiest way, but least flexible is using DFF Template. DFF Template was our initial attempt to allow affiliate to set and store template (color, font, background, etc...) into our database and given a particular DFF Template #. This DFF Template # can then be used in the DFF Javascript or Dynamic Languages calling line query string as an optional parameter. The GET query string variable is usually named 'style'. In the GET query string parameter it looks like this ...&style=12345... where 12345 is the DFF Template #.
  2. The second way to control styling is by using DFF's CSS PPC. We have created a different PPC which outputs certain CSS DIVs and SPANs which affiliates can combine or override with their own styling. We also call this PPC CSS our PPC version 2. How to use PPC with CSS compliant output. How do I determine which PPC version I am using?
  3. The third way, using DFFML + JSON, is currently still under development.

Getting RAW data from PPC
Sometimes no matter how much flexibility we provide to control output and design, they are just never enough to satisfy the pickiest web designer / programmer. If you are that picky, we hope you are willing to take up the challenge of having full control which means you will have direct access to the data via XML and JSON. Having raw data means you will be responsible solely to compose your own page layout and even the navigation and flow of your site. We recommend XML and JSON integration for medium to advance programmers only (or if you know a good programmer).

Downloading DFF's Product SKUs (data feed or database of products with unique UPC / EAN / ISBN)
We have a downloadable product sku data feed for advanced programmers who would like to have their own database of products downloadable via FTP.
