Dupe Detective
Receipt scanner for iPhone, iPad and Mac
Catch the item you paid for twice.
Scan your receipt before you leave the store. In a few seconds, Dupe Detective highlights anything rung up twice, so it gets fixed at the counter.
3 free scans and a 7-day free trial, then $4.99 a year.
Works with receipts from Costco, BJ's, Walmart, Target, Kroger, Fry's, Safeway and most major grocery stores. At Sam's Club, receipts save and your list works as usual, but Sam's prints a double scan as one line with a quantity of 2, so check any line with a quantity above 1.
Three steps. A few seconds.
Check the receipt while you're still at the counter, when fixing a mistake takes a minute instead of a phone call.

Get it fixed on the spot
Show the highlighted line at the register or service desk. Flagged receipts stay in Alerts.
A double scan takes a minute to fix at the counter. At home, it's a phone call, a drive back or a bank dispute.
U.S. shoppers say they're overcharged at checkout at least once a month.
