If you want a better price on a new product, sometimes all it takes is a little patience, my friend. But how long should you be willing to wait? I’m Doug Whiteman with your Bankrate.com Personal Finance Minute.

A product’s price will begin to come down either when retailers decide it’s time to put the item on sale or when the manufacturer decides a lower price is needed to boost sales. A site that tracks Amazon.com’s prices for video games says they tend to start getting cheaper just a few weeks after release. With electronic books, the main price drop generally comes when the paperback version comes out. Decide.com, a site that monitors TV prices, says nearly a third of new models see prices come down within just 10 days. It typically takes a year for an iPhone’s price to drop, while half of all new Android smartphones sell for less after a little more than a month. As for tablet computers, Decide.com says it takes more than two months for most to come down in price.
