How can I buy goods on ebay with bitcoin (So that I can make refund, if something does not work or it's broken)
Who knows the method?
Buy a Bitcoin Debit Card and then shop on eBay normally

Bitcoin Debit Card UQUID
https://bitcointalk.org/index.php?topic=1485950.0oh, +1 this one and also still if you don't want to own bitcoin debit card (don't know why some people wants direct btc transaction), you can ask here someone trustworthy to buy something for you from ebay or if you own paypal, exchange your bitcoins here. Otherwise there is no way to buy anything with bitcoin on ebay, nor amazon and etc.
