So buy it from steam legit and u wont have problems. also if u buy from another country their are exchange rates and credit card fees related to exchange rates and higher risk of fraud to deal all which will be added to your credit card bill and not show up on initial transaction. and remember if u buy in other country perhaps the keys may not unlock in your region and even if they do now they may not in the future when they crack down on it. the game is only on sale on steam and its not discounted.

too good to be true is too good to be true. so buyer ends up having his keys removed and the sellers has disappeared and will not refund. like when someone buys keys, then sells them and then does a charge back on prepaid credit card. Steam has been known to remove games from people account when the keys later turn out to be not legit keys. Best not to play around to save a few pennies and end up with the game removed from your account and out of money from some crooks that will never return it to you
