App offers don’t work – ampm Review

I have tried to redeem three offers at different locations so far and only one worked. Is it because the staff is not trained on how to ring up the items and scan the offers? It seems that no one cares to figure out what the problem is and just tells you that the offer is not valid. Updated review with locations that had issues scanning the coupon offers: 4010 Wible Road, Bakersfield, Ca 93309 and 3100 G Street, Merced, Ca 95340. Currently quite discouraged to try to redeem offers when no one knows nor cares what they are doing. Thanks.
