Hi ...
I try to look at it this way...some members gets paid once a week at there job, some gets paid every 2 weeks and some once a month. I always ask for payment in my listing to be paid in 7 days from EOA (End Of Auction) and to contact me if unable. Then I would make the call to file a UPI (Unpaid Item dispute..
It is your boat, you are the captain, its your call.
