Using Purse.io if the item never arrives, the bitcoins aren't released to the user who bought your item, so not a big deal. The guy is just wasting his time. Additionally, the user needs to provide the tracking ID.
I used few times Purse, to spend bitcoins and also to spend some amazon gift cards. I didn't think about stolen cards etc. I started to worry too since. But I have been told, it's safer to by item "shipped by Amazon". In any case, you don't deal with a person directly, you deal with Purse, so Purse if responsible. And you can also prove your case by showing your account history, to show you used Purse and it isn't you who used a fraudulent purchase.
As for Copay, sorry I don't know, but if it sells Amazon GC, it's surely for the .com Amazon version
Hmm okay, so you might not be dealing with a user directly, but someone on the other end is buying the product you listed & shipping it to you, right? How about the adresses it needs to be shipped to? They have to fill those in too right? I'm not so sure if that's something i'd approve of.
I'm not sure about Copay either but here is what I suggest:
1. Use Bitrefill. It's a very reputable service, I used them multiple times for different products and I never had an issue.
2. If you want cheaper gift cards (80-85%), contact Podgor:
https://bitcointalk.org/index.php?topic=1789747.0 He have gift cards/balance on a regular basis.
I'm not really a big fan of P2P deals since those usually end up going wrong, or have a big potential to.
Bitrefill looks pretty good. It's kind of confusing though, first the code is valid for all Amazon.com stores, but when you go to the USA section & actually try to order one it explicitely says that it is only valid for *usa amazon.
But when you then switch to the german "version/card", it doesn't say that.
The USA GC is simply called "Amazon USA", while the German version is called "Amazon PIN", and the UK version "Amazon UK" (Does this mean that the UK& GER version have no restrictions, and can be used everywhere?)
I guess i'll try bitrefill GER/UK with a small amount and see if it actually works.
