SellFire offers data feed services
Hi Efeezy,
My company, SellFire.com, makes creating a storefront out of Data Feeds easy. You create the store on our site and then just add a line of JavaScript to your word press blog. We also offer a dynamic store capability based on a pre-defined search. You can try it out for free to see if it works for you.
If you decide to go the manual route, a couple bits of advice on working with CJ feeds.
First, I disagree with plepco. I think CJ's data feed system is among the best in the industry. They have lots of fields, lots of delivery options, and you can customize the format. So, IMHO, working with data feeds on the CJ network is as easy as it is on any network (which is to say not very easy at all).
If I had one problem with CJ data feeds, it is the URL for each product points to a random CJ link domain (like jdoqcky.com). With each version of the feed the domain chosen for a given product can change. That makes it somewhat tricky to detect what products are new/removed with each feed version.
Best of luck!
Thanks,
Jason
