Costco offers its members the Lifetime 11x21-Foot Garage Shed
with free shipping
. (Non-members pay $150 more, so it's a far better idea to buy a 1-year Costco membership
for $55.) That's $390 under the lowest total price we could find for a shed of this size elsewhere. (Most merchants charge at least $3,450.) Sales tax is added where applicable. This shed is made of UV-protected plastic and steel with a simulated shingle roof. It comes with a carriage-style door, two skylights, six latch and lock windows, exterior padlock, and more. Deal ends April 21.
