Yes you can take it back. They will probably issue you a store credit or a gift card if you don't have a receipt. Walmart is very good about returns or exchanges especially if something is damaged!
Yes, you can return your item without a receipt. Here is Wal-Mart's Return Policy for items without a receipt. "To return or exchange items without a receipt, the customer is required to present a valid government issued photo ID. Information from the customer ID will be stored in a secured database of returns activity that Walmart uses to authorize returns. The merchandise will be returned and a shopping/gift card provided to the customer if the refund value of the returned merchandise is equal to or greater than $25 in value." I hope this helps!!!
