I have heard that there are some sellers of PayPal and WesternUnion transfers
You mean buying and selling PayPal/Western Union accounts?
Since he/she mentioned "transfers", then most likely is an exchange of some sort that involves those payment methods
[not a request for buying/selling accounts].
You'll probably get better exposure if you move this thread to the "
Currency exchange" board
[move button is in the bottom left corner of this page].
- Since you're trying to deal with reversible methods, you should always DYOR before dealing with anyone in here and also refrain from moving the conversation to somewhere else.
