Best Buy is launching a new price-matching guarantee.

Beginning March 3, Best Buy will match prices at all local retailers and nearly 20 major online competitors.

The chain wants to end so-called "showrooming." That's when a customer goes into the store to check out a product and then buys it online for a cheaper price.
