I made purchase of 5 laptops at Best Buy website on discounted retail price listed as Market Place product ,I paid $35 for express delivery but didn't receive anything.I reached out to Best Buy and they mentioned vendor cancelled the order & they said they will have to talk to the Marketplace Vendon which is Microcad Computer Corporation & take no responsibility for such action so why list them in the first place at Best Buy.Despite waiting for days and no response I called the vendor and they said they take no responsibility for any price error as it was a mistake where as now they are selling the same product 4X the price it was earlier listed.I would suggest its better to buy anywhere else other than this Vendor.First they list the product on discounted price and then they cancel the order and increase the price for their benefit and waste people time for no reason.
