When you check out at any store, it's practically universal that you'll be rung up by a scanner. This is a good thing for speeding up the checkout process, but a bad thing when deals aren't entered into the computer and you're overcharged at the register. The San Francisco Chronicle reports that Office Depot has been fined $2.3 million for overcharging customers in California at the register. As part of the settlement, Office Depot has agreed to offer five-dollar coupons in future sales circulars and refund five dollars to those who are overcharged again. Clark has his own system to avoid getting ripped off at the register. He doesn't allow anything to be rung until he has all items ready to go and he can watch the register. He loves self-checkout service for this very reason. Clark benefits from having a photographic memory when it comes to remembering prices, but he encourages others to write down the sale price or bring the circular to make sure they're getting the deals. Clark recently was at a store that rang everything up at retail price and only made deductions once it had all been totaled. It turns out he was overcharged $50 and had to have the order rung up again to get the right prices!
