Q. Shalom u’bracha:
Recently I purchased 2 items that the store failed to charge me.
The first was in Marshalls. I put on the register counter several items, to which the register person scans the bar code, and then bags it for you. When I got home I checked the receipt and realized that they didn’t charge me. Am I mechuyev to go back to the store and have them find the item to scan (I don’t have the bar code from the item anymore)

Second question: on a similar note, I ordered an item online from target. When I went to the local store to pick it up, they told me to wait until the purchase went through on their end. It took some time, and then they told me it went through and I can go. The next day I got a “cancellation email” that the order was not picked up and they refunded me the purchase price. Do I have to go back to the store and have them recharge me?
Thanks so much.

A. Horav Shlomo Miller’s Shlit”a opinion is that if a Kidush Hashem can be accomplished by returning the uncharged merchandise, it should be done.
