If he shipped it Fedex International it would be there already.
USPS is dead slow, I'd give it some more time to show before I jumped the gun.
On a side note: I mail a C/S check off every week to my Ex-wife, she lives less than 30 miles away in the tip of the sip in Southaven, Ms which is a suburb of Memphis, Tn
It takes 2 days for it to get there via USPS.
