There are the “12 Day of Christmas” and then something completely different — Best Buy’s “12 Days of Deals.” The special sales promotion kicks off today and runs through Dec. 20. “We know how hard it can be to find just the right gift at just the right price,” said Best Buy spokesman Keegan Shoutz. “We’re making it easier for customers by not only helping them find the best tech gift, but give them the peace of mind that it’s the lowest price of the season.”
