Walmart offers the Pit Boss Single-Burner Portable Gas Grill for $49.99 with free 2-day shipping. That's tied with our mention from two weeks ago and the lowest price we could find by $9. (Most third-party sellers charge at least $64.) It features a 305-sq. in. cooking surface, 10,000-BTU output, and locking lid. Note: Orders placed with free shipping by 2 pm local time on December 20 are expected to arrive in time for Christmas.
