I love this app and I use it almost daily. I have collected a number of gift cards that have been very helpful and rewarding. I would have given it five stars if the app would perform a bit better. Frequently the app stalls when trying to scan an item and after scanning the same item 3, 4, 5, 6 times it finally accepts the scan. Please fix that piece of it and I will give it five stars.
