What does Free Shipping really mean?
When you order $100 or more, your are really getting free shipping plus a 5% discount. This happens automatically. You don't have to do a thing. The free shipping applies to the 48 continental United States. The 5% discount on orders over $100 applies to all orders.
As you shop the Internet, be aware of sites that offer free shipping on individual products costing much less than $100. Why? Because, for example, if free shipping is offered on a product costing $30.00, chances are that the shipping is rolled into the product cost when the product cost itself was only $22.50. It's fine to pay the $7.50 shipping on a quantity of 1 but if you select 2, 3, 4 and so on, you are paying the $7.50 shipping multiple times.
