I agree with both of these comments. If I agree to buy an item I will pay immediately. I would not personally hold a watch longer than 24hr without payment unless a meet was arranged or something similar, cash etc.
My email asked about shipping, price and included info about a few recent trades I had done. I admit I did not say I WILL TAKE IT... but asking some questions when about to sent 000's into cyberspace isn't unreasonable i.m.o.
It was the 1st one sent, 8 mins after the thread went up .... 40 minutes later im told its sold. Anyway it's not the way i'd do it... and like I said i'll change the way I approach it next time.
