Have you ever seen something in a store and fretted over impulse-buying, wondering whether you could get it cheaper online? A new service, Frucall, aims to answer that question for you.

• Call 1-888-DO-FRUCALL.
• Enter the product barcode.
• Discover if you can get the item for less through one of Frucall’s partner sites.

If you register with their site, there’s more features available, like saving items for later purchase, and leaving yourself voice notes

We gave it a shot. It found us a copy of the Great Gatsby for $3 used or $9 new (shipping included). It didn’t return results for our olive oil or a pack of computer paper. Judging from the items on its partner sites, it should do fine for home items and electronics.

You can also opt to receive the prices by text message. Conceivably, you might be able to show these to the store and ask them to price match on the spot.

1-888-DO-FRUCALL, leave the L’s off for LaLa-I’m-saving-a-buncha-money.— BEN POPKEN
