Several years ago, I won an auction for a box of 50 Navy Arms .41 short. I sent payment and never heard back from the seller. After several months of emails to the seller, he finally stated that he was having to move from the state that he was in to Florida and that I would get my box soon. After more emails and a complaint to Gun Broker early in this transaction, I am still without that box. I finally found another, of course, for more money from a different site.
Ha, your case sounds exactly like the case with my mags. Guy claimed to be in AZ first, then claimed he was moving to Alaska & then just disappeared. Gunbroker did nothing.
