Aldi has not yet overcharged me.
Costco messed up 1 of the last 5 times I went. Their mistake was the most honest and forgivable. They somehow double scanned a Marie Calendar's Chicken Pot Pie.
Kroger has neglected to count all their Kroger Savings Coupons 2 of the last 5 times I've shopped there.
BJs has neglected to count all their Internet coupons 3 of the last 5 times I've shopped there. It's a known issue by now. The cashiers now even encourage you to review your receipt.
Meijer is the single worse. 3 of the last 5 times I've shopped there, prices on one or more items have rung up for something other than what they are marked. Always higher. And on a fourth occasion they didn't register an MPerk Coupon. Today, they actually gave me an $8 credit on a $2 over charge. So I'm not annoyed at having to wait in line to correct their mistake. But other times, I've had to have them take stuff of my purchase because they won't even discuss their own miss-marks.
As much as this happens to me, I can't be alone. At the very least, I know anyone shopping for the same stuff at the same place have same problem. With regard to Kroger one of the missed coupons happened to my parent on the same day. $2.29 half gallon milk was couponed up to 5x for $1.27. Coupon did not register for either us, a county away from each other.
I now have budgeted into my every grocery shop time the need for an extra 15 minutes to wait in line to have mistake corrected.
Theoretically in Michigan, I can demand extra compensation. If this persists, I might start doing so. Though, my only recourse if they don't honor the law it to quit shopping there. What are you going to do? Go to court to fight for $5? (or $250 as the law states, I guess)

Scanner Error Bill of Rights
The Shopping Reform and Modernization Act, or Scanner Law, requires that most items on store shelves be clearly displayed with the price; by signage, electronic reader, price sticker, or any other method that clearly and reasonably conveys the price to a consumer in the store at the place where the item is located. If an automatic checkout system (scanner) charges you more than the displayed price of an item, and:
the transaction has been completed, and
you have a receipt indicating the item purchased and the price charged for it;
Then:
You must notify the seller that you were overcharged, within 30 days of the transaction, either in person or in writing. Within two days of receiving your notice, the seller may choose to refund you the difference between the amount charged and the price displayed plus a "bonus" of ten times the difference, with a minimum of $1.00 and a maximum of $5.00. If the seller does not pay you both the refund and the bonus, you may bring a lawsuit to recover your actual damages or $250.00, whichever is greater, plus reasonable attorney fees up to $300.00. You may instead file a complaint in a small claims court without an attorney.
