First Class is the standard mail service. It's slow. It's slower with packages. It's also only been 3 business days since it was shipped. The only services I expect to make it in 3 days are Priority, UPS + FedEx. Even priority has its downers.
I just ordered mine a few days ago. But he was out of Passcards and he emailed me asking if i would go with the Superkey, or wait for the new Passcard3 (or 4, whatever it is) which is due in tommorrow (14th), and i told him i'd wait...so i couldnt tell ya, mines still waiting to be shipped...although i wish i had gone with the superkey, cuz my DS came in from nintendo repairs today, and my microSD is coming in tommorrow. so i'm really really anxious.
you can contact realhotstuff or even make an inquiry to the post office according to the tracking he sent you where the package is....although the post office is a hit and miss since they are not like the UPS, there are no detailed information during transit....just basically when the electornic billing is received and when the package is delivered.
unfortuantely, that is how long USPS can take in sorting out packages......just taly up yet another victim of USPS shipping.....I'm sure if realhostuff used fedex or UPS they could get a claim going a lot quicker and to send you a replacement....but they use usps to keep costs down but the downside is that sometimes this may happen to certain people.
