Why accept a partial refund at all? I don't understand you guys for accepting less than 100% of what you paid for useless crap as refund. Why not refuse the offer and contact Paypal? If you don't wait too long, and you should NOT wait too long, then Paypal will give you full refund. I'd never give a seller positive feedback unless he/she offered 100% refund (shipping and customs included) and even so I'd write about it in the feedback comment line.
