What do all of these numbers mean?

The list of numbers and slashes after the product indicates the discounts that we provide for quantity purchases. The first number is the price if you purchase 1 piece of an item. The next number, usually a "3" indicates the total price if you purchase three of the item shown and so on. The shopping cart will change the per piece price according to the quantity that you purchase. To verify the price after you input the quantity, click "update" and the appropriate price will be shown next to your item. Then you can click "Keep Shopping" to continue browsing or continue the "Check Out" process.
