Monday or Tuesday if it ships the current Business day and there are no customs holds
On west coast, EMS USED to arrive on Friday of the sale week from play-asia, but this changed about 2 years ago and due to customs holds and understaffing(?) it takes until Monday after the Thursday it goes on sale. Tack on another day, potentially, for the east coast. (I don't know what the guarantees for EMS are, however this is my experience with about 40 orders throughout the last few years with PA.com)
I've come to grips with justifying the added cost for Fedex for new games...if the game's not in my hand on a Friday, it's very likely I'll go out and spend quite a bit of money on the weekends (meals, gas, entertainment, etc)...an additional $5~10 is a small price to pay to prevent that
isn't that like saying the lunar cycle is a weather phenomenon...? :/
