If it is from a standalone seller on eBay and not a company that is a scummy thing to do. Though the gift card may be the way to go, I'd say any of those sites would work.

Yeah  I wasn't  sure  if I can refund eBay without it costing the seller himself. I guess I'll try gyft as it's a large company.

Large companies can take the hit somewhat, but smaller sellers won't be able to compensate for the loss. Good choice by not affecting smaller sellers.
