Best Buy announced that it will restart its price-matching policy on March 3, this time on a permanent basis, reports Bloomberg. (It previously ran through the Black Friday and Christmas season.) Designed to prevent "showrooming", Best Buy will adjust its prices on select products in-store and online (eligible items will be marked with a "Low Price Guarantee badge") to match retailers including Amazon, newegg, Crutchfield, Walmart, Staples, Apple, and more. However, the window for returning merchandise will be lowered from 30 days to 15 days. Google News has more.
