I purchased an AVR on eBay and the seller specifically said they would ship USPS, which I like because of their lack of brokerage fees at customs. I paid for the item and it's described shipping. The seller has told me the item has shipped but via UPS and not USPS. I know UPS will charge me about $45 brokerage fees. Should I hash this out with the seller before the package arrives or when it arrives should I decline it or accept it, pay the excess fees and start a PayPal dispute? I feel I'm not getting the service I purchased and thus entitled to compensation.
