"Won" a T/C new Englander on Gunbroker 1/9/15; mailed payment that very afternoon.

Bank records show my check cleared 1/21/15.

No communication at all and no rifle as of this evening.

Anybody ever been down this road?

Seller has hundreds of positive feedback comments, whatever that is worth.

Perusing his feedback, none of it is more recent than 120 days; dig a little deeper and in all that positive feedback are several scenarios exactly like mine here.
Lesson learned: actually read the seller feedback, don't just skim.

People always mention mail fraud; while I did mail the check, I used first class Priority - no signature,etc required.
