I placed an order about three hours ago and they have already sent me the tracking number. I hope that means it actually shipped today.
In my experience, it means they have actually shipped. I usually get my package (from RI to VA) in 1-2 days. The only time it took longer they still dropped it off right away and the post office was really really slow (even though it was sent priority)... even though it wasn't their fault, Mike sent me a discount code for a future order.
