Canceling an Order from Wal-Mart
Sign into your Walmart.com online account. The creation of this account is mandatory not only to order from the website, but also to track order progress and to cancel orders.
Look for the order you would like to cancel. The order contents will be listed on your account Main Page under "Recent Orders."
Click on the button next to the order number. This will show all the details of your recent Walmart.com orders. Orders from Walmart.com can only be canceled during the first stages of processing. Once an order has made it to the shipping part of the online ordering procedure, it cannot be canceled.
Look for a "Cancel" button to appear next to your list of recent orders on the Orders Details page. If this button pops up, you still have time to cancel your order. If you do not see a button, your order is in the shipping mode and cannot be canceled.
