Scan a product bar code and Decide analyzes its price history and volatility, as well as its availability. It also advises
you whether to buy now or wait up to two weeks for a price drop. If you wait, you'll get an alert if the price comes down.
Paying members ($5 per month; $3 a month for a yearlong membership) get a guarantee: If the advice proves wrong, Decide will
refund you the difference.
