AC7 supports three formats already, however the filtering options are more limited than what I need. So I wrote my own routines and added some new formats to support. Now I can make marketing feed files specific to certain vendors, specific price ranges or even both. Eventually it will support "Campaigns" where all the settings for the feed construction are saved to a "Campaign" for later retrieval. This will help immensely with maintaining a consistent CPC marketing program. Just select the campaign name and say "Go" - everything will be built just like the last time.
Anyone know of any other formats I could support?
PriceGrabber.com is out, they don't offer auto-categorization so you'd have to manually associate every category in your storefront with their category list. Great if you have 5 categories, bad if you have 210 like me

MSN Live is out, I couldn't even get it to work last time and it took 3 weeks for them to tell me it failed. You read that right, 3 weeks. If someone has used them recently and found better success, PM me your experience and I'll reconsider.
