The Best Buy Price Match guarantee is very helpful if you know what it covers and how to use it. However, most price matches have to be requested by you, the consumer, in order to take effect. Even if a price match within the parameters will result in Best Buy selling an item at below cost, they will still honor it. However, prices from Black Friday sales or other similar holiday sales are usually not matched.
The Best Buy Price Match guarantee does not cover prices from online retailers not listed above, products shipped from or sold by Marketplace sellers (third-party sellers), contract mobile phones, and a variety of other situations, such as mail-in offers, free items, free gift with purchase offers, deal of the day items, out of stock items, and open-box items.
