I had tried to contact you sometimes but I got no reply, so today I did successful bid of $293 for 15 of this to you on Ebay. I want to buy 30 of this for $480, if it's possible I'll cancel the bids so send me a invoice.
Even after contacting several times there was no reply, today at eBay you bid for $293 for 15 items. If possible please cancel that bid and I want to buy 3 pieces for $480 please send the invoice for the same.
