Can I return a product for a refund or exchange without a receipt if bought with bank card?

Yes but u do need an id

Yes

It's Walmart as long as it was bought there they will take it back

Most likely yes

Actual answer: depends on the item, sales, price, how long you had it and quality. If it's a phone, camera, laptop, gps, game, game console, and a couple other items with memory, it's 15 days with or without receipt, If it has a serial number they will look at t and see if it's returnable. If it has no box and has a serial like a prepaid phone, you can't teturn because the register has no way to deactivate it. So always keep the box. If the items is falling apart old or damaged it's not returnable even with receipt. If it's over 25-50 dollars it's up to the store and management team if they want to return it. If the item is from pharmacy like a diabetes checker, even if it's brand new, it's not refundable. Neither is body jewelry If you have done more than 3 returns without a receipt within a year you can't return anything without the receipt If the item does not scan into the register as in, "item not found" they cannot return your item without receipt.

Sure thing but if they can't find the receipt with your card you will likely just get store credit

Yes you can bring I'd and a copy of you card showing the purchase
