Tjoos: Somewhat smarter shopping

New shopping engine scans for quantity and coupon discounts.

Today I heard about Tjoos (no relation to Tjoon), a new price-comparison engine that adds a wrinkle to the standard model: It scans for quantity and coupon discounts.

That's the whole story, but it's a smart one. On standard shopping engines, like NexTag, PriceGrabber, and MySimon, you're given prices for single products (or boxes of products). Many consumer items are bought in multiples, though, and Tjoos' crawler deciphers the quantity discounts in the sites it covers.

Tjoos looks for quantity and coupon pricing, something other shopping engines don't. Too bad the only thing you can buy on the site now is contact lenses. CNET

Even for items that aren't usually sold in quantity (digital cameras, for example), the addition of store-specific discount codes to the pricing engine can make a fundamental difference for users. Other shopping engines don't pick up coupon discounts.

Tjoos reminds me a bit of Farecast (more), as it gives buyers a better overall picture of the market they're in. Tjoos doesn't show the quantities where the discounts kick in, though, which would make shopping for the best value a bit easier. It's still a neat idea.

In this early release, Tjoos only scans for prices on contact lenses. More product categories will be added later.
