Are there any plans for this payment method on GoG? It's all fine and stuff, but sometimes the credit card i use is at the limit and i'd like to use some alternative method to make a purchase.
On Steam if there is some excellent deal and my credit card is already at the limit, i can still buy PaySafeCard code using my cell phone and buy the goods. But on GoG i'm left out cold and the deal may be already over before the credit card state is reset (after being paid).
Some sort of "GoG Wallet" like the one on Steam would be a nice addition. So you can "upload" funds using PaySafeCard and then spend them as you go.

Yesterday PSC feature saved me from missing a pretty good deal on Steam so i'd like to have such option on GOG as well.

Any thoughts?

The question comes up from time to time, so GOG probably knows about it. They haven't said why they aren't adding it as far as I remember. Some people speculate that the vendor transaction costs for using PaySafeCards are substantially higher than for other services, which would be a valid argument against its inclusion.

Voted and added a reason why i'd like to have it as an option. Hoping for the best. Thx for pointing it out to me.

It's an old thread that I'm about to revive, but I'm happy that GOG did listen and they've added PSC as a payment method. My credit card reached the limit and I really wanted to buy Lichdom Battlemage. With no other way to get funds, PSC saved my bacon. Ordered a code via SMS and paid the game instantly. How awesome is that! :D Thx GOG!

Can I purchase a single order in gog, using my cc or paypal AND the funds on my gog-wallet

for example:

price of the item 59.99

balance on my wallet = $50
difference to pay with paypal or cc = $9.99

is this possible?

As long as it's GOG Wallet funds + some other payment method, I think you can do it (though I've never used the Wallet, so I can't be certain).
But I'm not sure you could pay part with credit card and the other part with Paysafecard, for example; I doubt it.

Yes, that is possible.
