I know this has been requested countless times but I cannot help reiterate how important it is to make this service part of GOG. Including Paypal will make the quick and easy buying option even more easier and quicker. Personally I'm itching to buy more than a few games but I can't because I don't have MasterCard. and VISA's "Protected by VISA" is abysmal. So to anyone at GOG: the quicker you can get Paypal implemented the faster you can have my money! :)

This sugestion was already notified and it's the most agreed wish in GOG.com's Wish List topic

I completely agree Toshi.
Paypal is the #1 feature many of us are hoping for.
I noticed you're from the US and wonder if you've tried the Paypal Plugin? ([url=]https://www.paypal.com/paypalplug-in[/url]) It supposedly will allow you to use Paypal wherever Mastercard is accepted. Hope that helps you, though anyone outside the US is screwed.

I did try the plugin and unfortunately I can't log into it to complete setup. I entered my email and password and security image exactly as it should be and the plugin keeps returning an error. "your login information is incorrect. please try again." I don't know why this is occurring...
