Selling poll: First asked or first paid?

[E-Revonut]

my opinion is you pm for price first, seller responds, then if you want it but can't pay at the moment immedietlly pm and tell when you can pay. If your the first to do this and can pay within a day or seller agrees to your terms your the one that gets it! But if you say you want it and agree on pricing you had better pay! I'm not sure if there is already a thread on here for posting your experience selling or buying from specific members there should be so people can see your record.
