Hi! I was shopping today at the location in Danbury and the cashier said that he will put the receipt in my bag and when I got home I couldn't find it. Can I still retur couple of items that don't fit if I used my debit card to pay?

If you leave the tags on and putting the credit to same card you used for the purchase. You can always ask to speak a manager if cashier doesn't know how to do it.

If tags are still intact I believe so

Yes u can with manager help

Yes you can return and exchange
