-Xbox 360 Premium Refurb for 249.99 with 2 year UNLIMITED EXCHANGE WARRANTY. Prices and year coverage varied by region. This means that if my 360 tanks (red ring of death), I can take it back anytime and exchange it for another refurb, and if that refurb tanks months later, I can take it back and get another one. If they do not have any refurbs in stock when I do the exchange, they give me a 249.99 gift card to be used for another new system if I wanted.
-Trade
ANY 9 games (as long as it's in their trade in database) and get an extra 25 dollar bonus credit in addition to the trade in value of my games. This is how I got my Wii
And when I say any, that means from any system even from two-three generations ago :O. Confirmed by several other cags.
TRU
Buy 2 get 1 Free. Bought a few Cube games for my nephew, 1 of which was Sonic/Monkeyball two pack so I ended up getting 4 games for the price of 2.

Blackfriday sale... BioShock PC for 25 bucks!!! However after playing that game, it is well worth the full price
Summer of Entertainment program, spend 100 bucks within a certain time frame and get a $10 reward zone certificate (when you normally have to spend 500 to get one). Due to a glitch, I never got one even though I completed the requirement. Called them and they confirmed that I never got it/used it and they gave me 1000+ extra reward zone points to my account.
