Currently i am selling Dell Inspiron 7720 laptop. I got a msg from a guy named james elvis. He mentioned his email id and asked me to reply on that email id about the price of my laptop in US dollars as well as shipping charge of fedex to ship my laptop to USA. He's ready to pay me $850 for laptop (by bank transfer) apart from whatever be the shipping charge. I don't understand, its near Black Friday then why he's willing to pay me that amount of money. I told him that if the shipping charge would be around $200 then i'll drop my price a bit but he said that $850 for the laptop is fixed and he won't negotiate. What should I do?
