While WinGameStore/MacGameStore may not seem a bad store at first glance they do have the nasty habit of selling games after they already ran out of Steam keys. Even though they advise you to wait at least 24 hours for the key to arrive I have seen many posts over the net who waited almost a week for their keys. It might seem as a minor issue if not for the fact that often a similar deal will appear at another more trust-worthy store and more annoyingly they'll charge your account immediately regards if you're provided with the product or not**. ** they also insist on refunding with store-credit even if they didn't deliver unless you open a dispute claim PayPal.
