So the other day. I sold a set of Tritton AX Pro's on flea bay for 120.00 (3day auction). Now I am used to having people pay pretty promptly after an auction ends (usually a couple of hours). But with this sale I am already at the start of day two and I havent had any communication from the buyer. I sent an invoice saying that when he sends the payment (depending on what time) I would more than likley be able to ship the same day as payment recieved. I know they say you should give somebody 4 days to make payment. What I want to know is would it be ok just to send a reminder saying something to the effect of "hey you have two more business days to make payment. If not a non paying bidder claim will be filed." Any advise?
