I've noticed that they usually submit the charges during Hong Kong Sunday or Monday. Seems like it's usually HK Sunday morning.
On Play-Asia shipping my experience with imports over the last 3 months has been that for the Fed-Ex stuff they will usually ship out HK Wednesday. I got my copies of Ikusahime, Phantom Breaker: Extra, and Fairy Fencer F all on US Thursday thanks to the date-line + release-1 shipping.
I did see that they shipped my Getsuei Academy hardcopy out on HK Thursday so I got that a day late on US Friday. So 3 out of my last 4 imports were same-day delivery. I am West Coast though so this might take an extra day for East Coasters, not sure how the domestic Fedex traces out after the San Fran drop point.
Personally I'm doing the same as Kurushii, got a Famitsu DX LE hard getting shipped, but I'm gonna grab a digital as soon as it's up.
As a side-note regarding Play-Asia's Yen cards, I noticed they seem to have a new system where they've uploaded scans of codes into their database so digital card purchases return IMMEDIATELY with your code. It's a nice change.
