Let's see...

The pudding guy was for Healthy Choice Pudding and it was AA miles. It helped make me a two million miler.

Then the ValueMags deal, then LatinPass, the 1-800 flowers thing, then savings bond flipping, then mortgage payments with money orders from USPS, then the United Chase bank multiple application thingy. Who can forget the USAIR software glitch (12 segments for CP) and the more recent and similar Priority Club glitch? Ah, what a wonderful source FT is for when the Next Big Deal happens. If the OP is thinking just from collecting something, like off food products, how about the 400 coke rewards points for a Sony camcorder or the early in the program DL awards? Current redemption awards are terrible though. Then there was the Wendy cups. Sometimes you blink (or after 4 hours on the Mileage Run forum) and the deal is gone. Sorry if I missed other deals. Usually the dinosaurs realize sooner or later someone is gnawing at their tail and the deals disappear. The objective is to catch (collect?) as many as you can and then keep your mouth shut to keep from ruining it for others.
