Hey Rick,
Just a marketing thought that may encourage the above retailers to increase sponsorship of your website. Similar concept to Cameraland and gr8fuldoug. Folks here are forever asking for current discount numbers to use for online transactions, re: $10 off $50 purchase, etc. Why not dedicate a thread on 'Classifieds' to the retailers that wish to sponsor it. For example, a Midway Coupon thread, a Cabelas Coupon thread. Then the retailers themselves could drop numbers in and participants could do so as well. Just a thought. And just a bump for you, this is a great concept you've put in place here. Congratulations on your success. I've been mulling a similar concept for a different marketing niche for a while now but it's like reinventing the wheel trying to put the concepts into cyber format.
