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've been shopping at GOG.com via credit card since Oct 2012 and have spent probably around $600-1000 CAD over time as a guestimate. The only very slight problem I've ever had was one of my first purchases I got a phone call from the security department of my credit card as my purchase at 4:00 in the morning was unusual and was through a payment processor in Cyprus. Apparently a lot of criminals use Cyprus financial institutions for fraudulent transactions so a lot of North American banks will put payment on hold until they can confirm with the card holder that the transaction is legitimate. Once I told them it was a legitimate purchase and that I may sporadically be purchasing from the same company over time they added that to my security file and I never had that happen again. I know many others who have encountered this so it is quite common for online shopping at new stores to trigger security phone calls if it is outside of one's normal card usage habits.
Aside from that, I have been shopping online now for 21 years roughly using credit cards, both at big retailers like Amazon, NCIX, Tiger Direct, various other online computer/electronics retailers, book stores, and even small retailers both in Canada and the USA. If it is a small business or unknown then I will research them online to see if they are legitimate or not, reviews, problems, etc. Rarely if ever do I stumble upon a fake store or fraud site. They're too easy to spot or figure out just by looking at the quality of their website, and some simple web searches to confirm their business reputation and legal status.
Some people are afraid to shop online with credit cards fearing their card numbers might get stolen or whatever. Yes, that is true, but it's also true if you go eat in a restaurant or anywhere else physically in person too.
A good credit card will have built in protection to the customer for purchase disputes, where they return the disputed money soonish, then they sort out who made the actual purchase and go after them with no consequence to the card holder. If someone is using a card that does not offer this, look for a better card seriously. All of my credit cards have this, free car insurance and a crapload of other benefits with zero annual fee and zero transaction costs.
So overall it is just as safe to shop online as it is offline in person, but just like one has to use their card responsibly in person, such as not giving the card to the waiter to wander off with for 20 minutes, one should not store their credit card number or details in an online retailer's website for convenience. It might be convenient, but it is very insecure and storefront security breaches happen every day even at the biggest stores. So if one avoids storing their card info online then there's nothing for criminals to find if they compromise a website.
The biggest threat to one's credit card or other financial details online is actually not the retailer or their website, but the person's own frequently virus and malware ridden computer that is shared between several people none of which have any real security sensibilities. :) Three solutions for that are:
1) Keep a dedicated computer or laptop (an older one is fine) for financial transactions online with a clean OS install, no video games, no general web browsing, and do not let anyone else use or touch it for any reason whatsoever. Do not install any 3rd party software unless it is absolutely required, and stick with software that is legally acquired directly from the vendor's own website or off legitimate CD/DVD. Don't use hacks/cracks/etc. downloaded from shady websites.
2) Alternatively use a virtual machine for this which is a compromise that is reasonable for most people who don't have or want multiple computers. VirtualBox is a free Virtual Machine software for people who don't already use virtual machines and don't want to pay for one or deal with limitations of free trials or similar. It's free, open source and works great for the majority of people's needs. It's just fine for banking/financial stuff.
3) If you only have one computer and don't want to use virtual machines, then make sure to practice secure computing practices and don't share the computer between people (as they're the weak link).
If all of that is too much to think about or deal with though for someone, then perhaps online shopping is best avoided, but it's 2016 and if one wants to benefit from the amazing amount of goods available at the click of a mouse then it's entirely possible to do so online safely and securely. There are always risks of course, but there are just as many walking into a store and using a credit card or debit card also. Google for "ATM skimmers" and "POS skimmers" for example to see how criminals insert an electronic device into the slot on a POS or ATM machine to steal one's card details when they use it.
That's all just general advice for online shopping safety, not specific to GOG. By default GOG has historically not saved any credit card info on their website, however I believe they have the option available now for people who prefer insecure convenience. :)
Some food for thought, hope it helps.
