I have shopped at many of these stores using the app that gave 3 to 5 dollars off. A cashier at another city a year back informed me of multiple uses you can do after you close out your items then pay and repeat until each 25 dollar transaction is paid for while redeeming your coupon. You have one hour only. I spend 200 and save a little money this is based on closing each transaction at 25 dollars then repeating until my groceries are gone. Jackie at the 99 cent store in Elsinore off of Central said her district manager said only one use when I tried this. I said they need to put this in writing because I have been doing this at the other 99 cents stores and never had a problem. I informed her each will be a seperated transaction and each will be closed out. During our transaction she didn't inform me she was going to leave the station she just stopped and walked away,spoke to a man I assume the manager came back without apology continued transaction with an annoyed face and frankly she was rude. I stayed focused. Sad,get your people informed and if you don't like what you do then change it. I said please,thank you,and have a blessed day. I don't work there but I do know how to treat people.
