During the check out process you will be given a choice of UPS methods of shipping. The most economical is ground shipping. The freight cost is calculated based on the weight of the products you have chosen, the UPS published rates,and your location. Generally, additional items will cost little more so the more.
For instance, 8 aprons cost $9.18 to send and 1 apron cost $7.18 so the more you buy the less shipping cost per item.
