Xenoplant777: So, I've been wanting to get something from this site for a while now, but I'm very paranoid about giving out my credit card info. Has anyone ever had any problems with GOG, as in, has their credit card info ever been stolen? I want to take advantage of this sale, but my paranoia doesn't help.
I pay with credit card from a separate user account in Linux. After payment i reboot my PC to clear RAM.
Never had any problems.
Same (or even better) level of security can be achieved with any livecd of Linux distribution (Ubuntu, Kubuntu, Xubuntu are the most famous).
Also, as was already said: GOG doesn't store credit card information. The only thing you have to fear is trojans/viruses on your PC.
