He literally just said he wants about $7 a key. G2A's such a popular site, it's pretty obvious he wants someone here to beat G2A's deal.
OP's evading a ban... he can disappear at any second, maybe not even on his own accord.
G2a's also got a pretty big record of having people sell game keys that were bought with stolen credit cards- not a big deal to most people, but half the gaming community tries to avoid them. I find lower prices elsewhere.

They still provide good deals, but buying from them practically hurts the devs- the stolen CC charges back, cdkey is still active, dev loses money.
I had a few keys a week or two ago, but I don't have them right kow; i'll contact you when I get them back in stock.
