This is why I don't understand the sellers (here and other forums) who simply say "whoever sends me the money first", sometimes without even confirming what email address is associated to their paypal account. Then multiple people end up sending money and you have to deal with refunds. I guess that means I also don't understand the people who send money without even knowing that the item is exclusively theirs or that they have the right email address, but that's another conversation 
I usually contact a seller, if I have a question I'll ask it, or say "I'll take it; please confirm your paypal email". If I have a simple question, I may say "If it's the one with the red PCB I'll take it....". I guess I've lost a couple of deals over the years because I don't throw money at people without confirmation but I've probably saved myself a lot of hassle. Generally, particularly in some of my photography forums, the seller has a pecking order of people who said "I'll take it" which doesn't require throwing large sums of money around haphazardly to be a part of. I guess every site has different cultures and norms....
Enjoy your PBT caps!
It's a hard knock life on these forums. If you aren't camping the classifieds, you aren't getting anything good! Just ask tsangan

For some reason, I thought of this song when I was reading this post...
