Never user you credit information on G2A and the like.

That's G2A Shield pretty much.

What happened? All money gone from you bank account?

You probably missed a nano-checkbox hidden somewhere during the process. Also they have the nasty habit of respawning when you are sent to the next page. Always make sure to opt-out of all these "offers".

But for all intents and purposes and for the love of God, don't EVER use your CC details on such sites. Resist the deal no matter how good it is so you won't regret later. Even if supposedly they don't use it in a shady way, their security might be lacking and someone else can get a hold of your data at some point.

If you truly want something and you must buy it from there or any other place for that matter just use PayPal. At least you'll know where to point your fingers to if something nasty happens with your financial details and you have complete control over your subscriptions.

I use only PayPal pretty much anywhere. Except in Finland, since we have different system here. More secure, i suppose.

Yep. Paypal is pretty safe
