what is the cheapest way to ship them out? If I sold a pair of jeans with a shirt or xbox etc..., what would be the cheapest method of shipping?
UPS or Fed-Ex Ground the is not CHEAPEST way, but it is the BEST way to ship. Shipping via Fed-ex or UPS gives you COMPLETE traceability or your shipment and saves you TONS of headaches down the road if your customer disputes receipt of the product and tries to reverse charges on you via PayPal or any other online payment vehicle they may have used.
