I listed a pair of my daughter's UGG's which closed on Sept. 27; clearly stating in my auction (and invoice) that payment was due within 3 days if paying by Paypal; 7 days if paying by mail. O feedback buyer wins the auction, no response in 7 days, so I file a NPB. 8 days later (yesterday) I filed for my Final Value fees (saying I no longer wished to communicate with buyer) & was credited my fees. Then she paid today using Paypal???? No explanation, no kiss my a$$$, no nothing after all this time. I refunded her payment, since I frankly would rather donate the boots than sell to her at this point, but am wondering how can a NP bidder pay after a credit has been issued by eBay and a dispute closed? Can she still leave me neg. feedback? Can I get in trouble for being a non-performing seller?
