Net Shops Affiliates

We have found our most profitable affiliate programs through here.  They have over 50 to choose from.  Features include 10% commissions, a support forum and real-time datafeeds.  High quality goods plus high payout.

LinkShare.com

Contains our two highest-converting programs: Target and Wal-mart, though commissions are lower than NetShops.

Share A Sale

Has several decent affiliate programs worth joining.  Some include datafeeds.  Interface is less intuitive than Linkshare or NetShops, but I still recommend it.
