Best online shopping experience I've ever had. Extremely knowledgeable staff when I contacted them with a query, they don't sell any junk so everything you see on there you can trust, and they say delivery will be several days but in my experience usually have your purchase to you the next day.

Trustworthy and reliable.
I've used them a good few times now, they have some good deals but the trust factor in particular is excellent.
I should mention they have a really good UI. The integration with Steam and Uplay is easy and breezy. I really like the Uplay connect feature where you can automatically redeem games on your Uplay account just by logging in. (and it keeps you logged in if you like)

Great site, I really recommend them.

I'd recommend avoiding them as I believe it is unsafe to trust them with your money.

I've made three purchases from G2A with no specific problems aside from the way they constantly try to badger you into buying G2A Shield.

But this last was a game code which Steam tells me is already in use. I've reported it and got no response inside 26 hours. No refund, no apology.

Some of the worst customer service I've ever spoken to. I bought a couple of Office keys that were already activated. An hour and twenty minutes on webchat to get the support agent to acknowledge that "valid key" does not fix the issue of a valid key that has already been activated.
I used them a lot before this and the keys were always good for games, but now I'm a bit unsure they can be trusted.

Oh also, I forgot to mention. I'd sent a report to paypal, they'd contacted Kinguin and both my orders were marked "refunded." But when I spoke to Kinguin on webchat to check how long it would take, the support agent told me that in this context "refunded" did not mean "refunded." It meant sometime in the next 20 days someone would take a look at my report.
