So I purchased a few cards from a board member, who shipped them Priority USPS with tracking and delivery confirmation. Seller is totally reputable with several prior transactions. USPS says the cards were delivered on March 4 at 11:16 am. Only you'll never guess.....
They never got delivered!
Did a Google search and am further sickened by the number of people who got "delivery confirmations" without ever getting their items -- or their items were severely delayed beyond the date of delivery confirmation.
Apparently I'm at the whims of the postman with his electronic delivery clicker.
I'll keep y'all "posted", but it doesn't look promising...
