Back in 2004 I set up and optimized an affiliate page with a $250 rebate offer on a $997 physical product. Attracted a 'waiting list' of 200 prospects and mailed 3 phases ... made 22 sales, minus 2 refunds = 20 x $250 (after rebate) commission -> $5K from a list of 200, 6 years ago. Not too bad, eh?

Cheers,

Mike
