I don't know who this vendor is.. but from the sounds of it glad I never did business with them. I must be lucky because in the last year the 3 places I have ordered from always shipped the next business day after my order was placed and always received items in 2 days (partially due to living in central MO) with 1st class USPS...
Some things to keep in mind with USPS tracking...
1. It blows... it is never current, seems about 24 hours off and you are lucky to get a time stamp on more than when pistage printed and delivered.
2. Very inconsistent... seems like sometimes I will get the received/processed/departed, sometimes I am lucky to just get one, no matter which USPS service the package was sent.
3. If it says shipment accepted, the usps has taken possession of the item.
4. I have had items that said no tracking avail. all the way up till the day after delivery when *poof* all info was up there.
5. You used to be able to check up to the minute by clicking non the little (!) Thing next to the tracking number... the last few updates apparently killed this.
6. I have a package that according to track and confirm, they either misplaced, puton wrong truck, or the ttruck broke down... I have also had a package go from out for delivery, to departing sort facility back out of state, and back again (was express mail on top of that, which is why for my gunsmithing business I only use UPS and FedEX anymore.... FFL holders can ship usps) and added 3 days.
