[quote name='cheapfrag']The combo of McD/Best Buy $5 off PS2 coupon and the EB Games Trade-in 3 PO games and get GT4. The combination allowed me to build some EB credit (for about a quarter on the dollar) and also get a copy of GT4.[/QUOTE]
I like the idea of combos - this combo, as well as the EB/TRU green-tag combo from very early in the year (Feb?). GT was at 90% (eg, $1 for Mojo) and EB had their $10 bonus for 2 trade-ins with the only restricted titles being yearly sports games. That was my first big deal, and the first time I had ever traded in games. I used it to fund half of my PS2 and DS system purchases.
But, hands down, the Gamerush Trade 2 Get any New Game (first part of 2005) or Preorder (nearly all year) for $29.99, in combination with SEVERAL other deals (TRU 90% GT, CC $1.99 summer clearance, etc), was BY FAR the best deal for me. I was able to preorder just about every PS2, Gamecube, PSP, and DS title I wanted from early Spring though mid-late 2006 (Zelda and FF XII, I'm looking at you!) for around $12 out of pocket (since, for those who don't know, you also get the trade-in value of the games).
The TRU Dec clearance is nice for those who could find anything - the only game I got out of it was WarioWare for GC, and some trade fodder for Gamerush (Ghost in the Shell, King of Fighters Maximum Impact, things like that which are still sitting on TRU shelves). I just hope that doesn't win simply because it is the most recent good deal.
Since GR deals are somewhat limited due to location, I would probably put the EB Games $10 bonus deal (in combo with the TRU 90% GT) as the best - as that was available to pretty much everyone in the US.
Overall, though, 2005 was a great year to be a CAG - I'm glad I joined right at the beginning of it! Sure, I missed the classic Circuit City $5 sale (Summer 2004 - being an ignorant gamer back then, I went to it after it was advertized in the paper and found out to my dismay that all the good stuff had been purchased prior to the sale date by people with lists from the Internet - probably some of you bastards

) but I more than made up for it this year.
