So, long story short: I bought a Transformer on eBay, the seller's feedback is overwhelmingly good compared to his neutrals and negatives. (He has maybe a handful of those over the course of a year, compared to HUNDREDS of positives in the last year, alone.) I paid roughly $20.00 for shipping, via Priority Mail, which is the going rate because it's a heavy and awkward item. I paid for it on Friday (the same day I bought it) and he waited until Monday to ship it. But wait..what's this? It's being sent FedEx SmartPost?! I contact him, he confesses and tries to blame the USPS for damaging his packages. So what should've been 2-3 days will now be 8-10 days, which pisses me off. He offered a refund of $8.00 for the difference, I've accepted and now he's gone radio silent. What should I do? Do I contact Paypal, do I contact eBay, or both? Do I refuse the shipment, do I hound him for the $8.00? Normally I wouldn't care too much, but this was a clear bait and switch and he admitted he changed it on me. What would you do?
