Well, I would stay on top of it and request a tracking number.
I just sent out a really nice procharger system to a guy in Lousiana. I have shipped a ton of stuff and usually 3 to 5 days delivery to buyer is tops. The procharger did not arrive as estimated by USPS. USPS said it was lost in mail.
I am always concerned about every shipment. I always insure the package, require a signature upon receipt and always submit a valid valid tracking number to buyer on day shipmenyt is sent out via email.
The buyer was very patient knowing through the USPS tracking process the item did show that it was dropped off for the inital delivery, but no status there after.
I got the post master involved after day 8. Day 15 postmaster informed me that he could not find package and that I would have to file a loss insurance claim 21 days after date of drop off.
You can only imagine how upset I was by now. Here I had a very nice guy who sent me his hard earned money for a nice procharger and he had not received it in a timely manner and now it is reported by postMaster to be lost.
Out of the blue, on day 21 the procharger was delivered, buyer happy with product and I was able to wipe the sweat off my brow.
Just goes to show you, no matter how well you try sometimes there are hurdles to jump.
