Read their order issue thing. It stated if your order is showing still packaging 48hrs after clear payment, it wasn't in stock and they need 2-5 days to replenish stock.
Basically they were out and are waiting on it from China or they just haven't updated your shipping info. I'd email them and see what they say.
You'd have probably been just as well off to order from
fasttech, dhgate, alibaba, since they are probably doing the same thing.
Be careful of any company that has anything about dropship, means they sell things without actually stocking them. You order from them, they order from whoever, and the whoever ships to you.
