I sold my Bricasti on Thursday for $2,800.00. Friday, I was in the studio all day and didn't cancel my eBay listing. Friday, a got a PayPal payment for the $3,200.00 listing on eBay. Having given my word to the guy I sold it for $2,800.00 , I had to refund the money to the Ebay buyer which included a $93.10 PayPal fee. It was bad luck that I lost out on a bigger sale, but I should have immediately marked my other listing as SOLD. So, don't be like me. Mark all you listings as SOLD, or make them inactive as soon as you sell something. Lesson learned the hard way.
