Ay, I use USPS Priority for all my eBay auctions, and I've never had a problem. UPS on the other hand... ugh. Let's not go there.

FedEx is good, but a little pricey.

It seems you just have a lazy letter carrier. One man doesn't bring an organization like that down, IMO. Oh well, what can ya do? Guess you'll just have to wait for some good ol' fashioned Postal Violence down there at your local station and maybe they'll take out your letter carrier.
