Where do online shops like and http://www.gamecards.eu/ and http://www.shatteredcrystal.com/ get their stuff from?

I am planning to open a small internet shop with similar content - CD keys for online games, prepaid game cards, and such, with instant electronic delivery after payment. But my main problem is finding a supplier who I would buy games and game cards from.

Game publishers I've tried contacting will not work with a small and unknown company, and buying from other online shops in bulk, even through affiliate programs and such just isn't profitable because of expences associated with web-site hosting, paying support staff, etc.

So where, where do all those cheap games come from?!
