if a price of something differs by more than 10℅ by currency or region the sale is blocked to gift. Along with stopping people buying things and putting in thier inventory.. I gather its more against the grey area market of cheaper country pricing sold for profit elsewhere.. But its really stopped me gifting games to good friends overseas..
Thanks for the info..ill buy from here :)
