Hi. I bought the protein drinks premium and I received a card from Costco regarding these drinks and to return them but I can't find the receipt. Can I still returned them?

Yes, they can look up that you bought it on your Costco card

Absolutely! When it comes to customer service and returns this company supercedes any in my book

Yes ,of course

Yes, go to customer service and they check whit you card on the sistem and they return your money

Yes
