Another problem for the buyers of items from these drop shippers is the possibility of Customs fees, taxes and possible taxes for an item that was supposed to be a domestic shipment.
if you have to open an item received dispute to get your money back, state that item location n specified as Canada, shipped from Singapore.
also, go to the completed listing and click the report button and report the seller for item location misrepresentation.
Drop shipping is allowed, but the item location has to be the location of the drop shipper, not the seller's location.
