Guy who says I'll take it and pays within a couple of days (unless specific arrangement is made.)

I've had a few times where I agreed to buy something (not on RCM), but was unable to pay at that exact moment (like @ work or whatever) go home that night and get a message that someone else got it bc they paypal'd right then. That's a dick move by the seller IMO.

If I agree to buy something explicitly and then don't pay or contact the seller for a couple of days, then deal is off IMO.

Also, the agreement has to explicit. One forum people used to just rush in and call dibs in a post and never PM the seller to work out terms. Then all the other people PMing get put off and leave the seller in the lurch.
