Think of your shopping cart as an online version of a real shopping cart that you would use whenever you go to the store to buy groceries.
Just like a real shopping cart, you can add items, remove them and change the quantity of each item if you want more than one. To add an item to your shopping cart simply click on 'Add To Cart' and you will be taken immediately to your cart. Here you can make adjustments to any products you may have chosen, and can remove any that you added by mistake. You can then either checkout or continue shopping. If you want to access your shopping cart without adding a product, simply click on the 'View Cart' button available in the 'Shopping Cart' box.
