Better be careful. Walmart will get the number of the person on the paypal account (don't know how.) and will call that person and ask if they made the purchase.
I tried several times to buy stuff on walmart.com with paypal and 30 minutes later the order is canceled. PayPal has never limited my account for this, but from reading here they have limited some folks account.
Stay away from Walmart - PayPal unless you want to loose your PayPal balance.
