The Shelf Says Sale. My Phone Says Do Some Paperwork.

You see a sale price on the grocery shelf. Good. You pick up the item. Then you notice the smaller words: digital coupon.

So the price is available, but first you have to tell the store you want it. In an app.

That’s a strange amount of ceremony for a jar of peanut butter.

To be fair, paper coupons weren’t exactly a triumph of civilization. You had to find one, cut it out, remember to bring it, and hope it hadn’t expired. Digital coupons get rid of the scissors. They replace them with a phone, an account, and a little button that says “Clip,” even though nothing is being clipped. We’ve kept the vocabulary of the annoying part.

If you already have the store app set up, fine. Tap the coupon and move along. If you don’t, your grocery list now has an unexpected first item: establish a relationship with the supermarket.

Download the app. Create an account. Maybe confirm your email. Find the coupon again, assuming you remember exactly which peanut butter was involved. Then make sure your loyalty account is connected at checkout. All this so the register can learn that you did, in fact, want the lower price printed six inches from the product.

The oddest part is how normal this sounds now. Someone could ask, “Did you clip the peanut butter?” and everybody would understand that no scissors were involved. They’d also understand why you were standing in the aisle looking at your phone instead of buying peanut butter.

Stores are allowed to run promotions. Nobody is demanding that every jar cost the same forever. But when the shelf announces a discount that requires a separate action, the shelf is doing a little advertising and leaving the administration to you.

And you can’t always tell whether the discount worked until the register totals everything up. At that point, checking the price means reading a receipt while other people wait to buy their groceries. The savings have acquired an audit phase.

I’m not asking for a return to clipping coupons at the kitchen table. I’d just like the price on the shelf to be the price I can get by picking up the thing and paying for it.

Instead, the peanut butter is on sale, provided I’ve notified the peanut butter department.
