Buyer is a douche for not reading the listing, but if you sent me that many invoices/ messages within the first 5 hours I would make it a point to wait till the very last minute of the 8th day to pay you.
File an unpaid item case when you can. Then close it asap. You get your fees back and the buyer can't leave feedback if he doesn't pay. There is no reason the buyer needs to pay the fees other than an idiot tax. You won't be out anything except time and frustration.
On the lookout for: Vick Ballard Topps Magic Black Border Auto /5.
Any other Ballard SP autos.
