Best Buy discounts a selection of items as part of its Blue Sunday Early Doorbuster Sale, with prices starting at $49.99. Even better, all items receive free shipping. At up to 38% off, that's among the best sales we've seen from Best Buy in recent months, yielding several price lows, and the first Doorbusters sale we've seen from Best Buy since the Spring Doorbuster 2-Day Sale in March. The sale features discounts on such items as laptops, HD televisions, and tablets.
