Mine is Steam because it has really good sales and I pay with dollars.

Mine is Steam because i don't pay with dollars and it has good sales

My favorite are bundles.

I think Steam is a pretty cool store. Eh has nice sales and doesn't afraid of anything.

Mine is Steam Gifts because all games here are free. :)

thepiratebay (just joking)

Greenmangaming and Amazon as they've had some really amazing sales lately.

bitgamer

I really like Indie Gala.

amazon, they have insane bundle deals, checkout is easier than steam but annoying that you can't load up your cart or checkout with items on one bill. Plus no support for international cards

Greenmangaming does not accept paper currency (dollars.)

Amazon and GamersGate

Mine is Nuuvem cuz I pay with brazilian Reals and it has really good sales, but no Paypal atm :(

GG. I tried GMG but most games i want, require that capsule bullshit.

GreenManGaming. : ) I earned about 60$ writing reviews on that site. Love it!

Some Lithuanian internet stores. Borderlands 2 for 22 dollars, ho!

I've had some good deals in g2play back then.
There also was this place where I preordered Borderlands 2 for half the price, but I can't remember what site it was :/

Everywhere who has cheapest games

Steam

I can only afford steam games :(

gamersgate!

Greenmangaming because I can pay in dollars and great offers (got Just Cause 2 for free by trading-in few games).
