Due to the rising cost of shipping we changed our FREE shipping on purchases of $150 or more online instead of over $100. Since shipping is not what it was before we are offering you a choice to have your package ship UPS or Fed Ex instead of free by USPS, but at a cost of $15.00 whatever your total is.
