Do you use Steam or GOG to buy games directly, or just buy game keys on other sites like cdkeys and GMG ? Personally I've been using the cdkeys web site, unless there's a discount or a free game on offer on Steam/GOG. I get games far cheaper that way, usually anywhere from 20 - 30 %, and I've never had problems with activating games bought on their site. However, some people have apparently had problems with the games they bought this way being deleted from their steam account and/or having their steam account banned. Your thoughts ?
