I know you mentioned there was blame to both sides, but in fairness, TCC's joking tones earlier in this thread were just as out of place, if not more so. Given how long the process has taken, I don't think you could really fault Polonsky if his patience is beginning to wear thin and he makes a little wise crack here and there.
I said it before and I'll reiterate it again, this is one of the faults that both sides are guilty of. Both parties are to blame for the back and forth regarding the address. TCC knew he was going to need the address to ship on time and should have asked for it. You knew TCC didn't have your address and should have reached out to provide it. When I cement a deal, payment and address are the first two things I provide within a day of invoice.
(Side note, I know you cc'd TCC, but given his prior statement that he doesn't "read the boards", perhaps a PM or a reminder via Instagram would be more beneficial. Otherwise, I can just see him coming back and claiming he didn't see this post until next week.)
I think this right here was the problem with the post.
If it's a trusted seller, I too prefer payment via check. Books are expensive, I don't like paying another 3% in PayPal fees. (And yes, I realize the fallacy in believing in a "trusted seller" given the actions we've seen from two recent boardies.)
