Hi I've purchased the retail version of the game (from Amazon) and already have redeemed my beta code. The thing is, I don't live in the US and was relying on a american friend of mine to mail me the game once its released. My question is, should I cancel my Amazon pre-order and pre-order it via PSN? What about the beta key I already redeemed? It would be much easier for me to order it via PSN but I'm afraid that something could go wrong since I've already have one beta key in my account. What do you guys think? Thanks for your time.
