What a lucky lad
quick story...
A friend sold a $3000 guitar on Ebay and took PAYPAL...He shipped out...Buyer denied payment so seller was a had lad...Buyer kept the guitar and then for what ever reason the buyer sent the guitar back in the same condition as it sold!!!..
Of course the buyer kept it 3 months...I guess he was on tour and needed it or wanted to try it out.... Moral of the story...Cash talks and PAYPAL walks!!
I would say however it is good for a deposit with a time limit to come and get the item..
Also I would suggest a seperate account for sales only...If you do enough....
