Etsy pretends they will support the purchaser, but look closely at their rules: you have the burden of proof; you can't get a refund if you purchase via PayPal, and they encourage PayPal; you can't complain in their forums, but the forums are the only way to get answers.
I suspect there are good vendors in Etsy, but the ones I found were crooks, plain and simple, and Etsy did nothing about it.
