Due to Walmart's address mix-up, I've had to pay about $60 to return my item. Although the correct address was listed as the "preferred address," their system shipped to a previous address. Customer service was not helpful. They blamed the mixup on the vendor, yet their system handles the address. I use Amazon a lot for my current home project (>$1000 in the last 4 months) and have had no such trouble there. I strongly recommend against using Walmart.com.
