Most of my economy shipments usually take about a week and a half to arrive (and I live in the eastern US), but 2nd OG took three weeks, for some reason. Bad luck in customs, I guess. --- "Brush away those tears underneath your mask!" Segata Sanshiro...gone, but not forgotten.
If you are moving in less than 3 weeks, I would wait, otherwise go for it.
Either way, I would shell out the extra cash for fedex. I have ordered quite a few things from PlayAsia, and I like the speed and peace of mind (tracking, insurance etc). If $15-20 extra on a game is going to break the bank, perhaps importing is not a field you should get in to.
