The smell of barbecue tells you that it's summertime, just like the crack of a baseball bat or the sound of a reindeer lapping up expired eggnog. Add fuel to the season with this Groupon.
$10 for 20-Pound Propane Tank for Grill with Delivery and Exchange ($20 Value)
Technicians swing by with a filled propane tank and haul away your empty tanks, as long as they're in working order and possess a triangular OPD valve. You'll also be automatically enrolled in the rewards program, which merits $3 off every third tank exchanged.
The Propane Express
With its doorstep delivery system, The Propane Express ensures that no barbecue is called off for lack of fuel. Staffers arrive at their clients' locations to present them with propane tanks, then tote away their empty tanks to save clients the hassle of lugging them to the refill station or replenishing their supplies with helium from expired birthday balloons. Customers simply indicate where they're leaving the empty tank, and the delivery workers will perform the switch even if nobody is home.
