I can send you the email that comes directly from Walmart that has the barcode. You can print it out and take it into any Walmart and/or Sam's Club and use it just like an actual card at any register.
If I hadn't already purchased it online, I wouldn't mind shipping one, but I already got this one. I'll be listing another one this week that I can purchase from the store, but if you have a printer, you can just print it out and use it just the same. The information is all on there for them to scan the barcode, and it will deduct the amount from your bill.
