After selling Farecast to Microsoft, Etzioni launched another price-forecasting service calledDecide.com, which uses even more data and analytics to predict future price changes on a whole range of consumer products. Today, for a small subscription fee, you can access Decide.com on your computer or your smartphone, and find out whether the price on an item is likely to increase or decrease in the next two weeks or so. For instance,

• If you’re considering whether to buy an Apple iPad, Decide.com predicts that the $499 current price for the iPad Gen 4 will likely drop by $53 within the next two weeks (82% confidence). So you might want to wait a few days before you buy.
• Or if you’re thinking about an expensive Precor Elliptical Trainer for your home, be advised that the EFX 576i model, currently priced at $2999, is likely to increase in price by $233 within two weeks (75% confidence), so you’ll save money by buying now.
• Need an infant car seat? Decide.com predicts (with 96% confidence) that the $290 price for the highly rated Chicco KeyFit 30 will drop by $96 in the next two weeks.

And by the way, these are the predictions on Decide.com as of early Monday morning, July 8. But they change regularly, as new data come in.

Once Amazon is in this mode it's curtains for Decide.
