. That's tied with last week's mention and $153 under the lowest shipped price we could find today, aside from the deal below. It features a full-sized tap and regulator with gauge and it accommodates up to a 15.5 gallon 1/2 keg.
Orders placed by today via standard shipping are guaranteed to arrive by Christmas; however, it states that in-store pickup orders will not arrive by December 24.
Update: As a reader discovered, Home Depot has it for $299 with free shipping.
