Another problem is USPS is unreliable in ever scanning the package if you do have tracking. I've had numerous packages that showed the label was made and is "pending" receipt of the post office. Only for the thing to never get scanned until the day it hits my local post office for delivery.

its been less than a week, even if you did agree to tracking and he misplaced the receipt, atleast be patient enough to allow the thing to run through the system for a bit.

I'd be more worried if your transaction is like a current one of mine.

Purchase the item w/ "free 2 day shipping". it gets "shipped" at 2am shippers local time (california) on a saturday. It then got marked shipped with no tracking information. When i asked them what the tracking # is, they say they dont get that until the shipping service picks it up and they'll tell me when they get it. When i asked who they were using, its been crickets ever since. Top it all off, that free 2 day shipping, there anticipated delivery day is Sept. 1, it was ordered Aug.19, that'd 9 days excluding weekends..
