Back in five minutes. Walmart's No Receipt policy applies to items returned in a store only. When you return an item without a receipt, you have the option of receiving a cash refund (for purchases under $25), a Gift Card for the amount of the purchase (for purchases over $25) or making an even exchange for the product. You should be good to go. StickMane and ghj like this.
I know Walmart will accept items as returns if you don't have the receipt, but I am not so sure you will have any luck without the packaging. They use the barcode on the box to confirm it was a Walmart product and then issue a refund.
