Well, I go back as far as I can remember:

Wii- Wife got it for me for my birthday at Walmart

GC- EB Games

PS2-EB

Xbox-Best Buy

Dreamcast- EB

PSONE- Funcoland (I think thats what it was then)

N64- Funcoland

Saturn-Funcoland

SNES- Pamida

Gensis-Pamida

Sega Master System- don't recall

NES- Pamida

Vectrex- not sure

Atari 2600- Not sure, I was about 6 years old.

I've traditionally bought games for most of the systems at EB/Funcoland for the most part, trading in games I didn't like or got sick of and buying new ones.

NES at toys'r'us
SNES at TRU
N64 at TRU
GC at TRU
Wii at TRU

Wii games at TRU and Best Buy

I usually go to Target but I have been known to get my games from Game Stop even though I hate them with a passion. You can throw in some Best Buy and Wal-Mart in there as well.

Circuit City - Wii, some accessories, 3 games
Amazon - 5 games
Best Buy 2 games, some accessories
Costco - 1 game
Target - 1 game
Deep Discount - 1 game
Used from a friend - 2 games
Gift - 1

Gamestop and EB games.....

My parents managed to find a Wii in December 06 in the big Myer in Sydney

But most of my shopping
JB because they're usually the cheapest
Game and the gamesmen (and EB games to a lesser degree) if the price is the same because I like to support actual game stores

I got my Wii and ds. Most of my games i got at Wal-mart, Hastings or Gamestop. I do get some from best buy though.

I usually buy used games at Rogers video during promotions to trade in at EB games for a profit, the trade in value generated is then used to buy/prepay games I want. It's worked very well so far. I only buy new games.

I buy nearly all of my games secondhand. If I buy them new, they are either from Amazon, Walmart, or Steam.

I bought my Wii and PS3 from gamestop.

i mostly buy em at wal-mart
