Gaseous propane becomes a liquid when pressurized, in the same way that marshmallows turn into coal when heated. Refill your most efficient marshmallow-roasting fuel with today’s Groupon: for $10, you get a propane-tank-exchange delivery from Propane on the Way. Its service area encompasses zip codes across northern Virginia and Washington, DC.
Propane on the Way’s combustible couriers deliver fuel to needy barbecues and cart away empty tanks for reuse across their far-reaching service area. The delivery people haul tanks filled with 17 pounds of propane to each customer’s doorstep, curb, backyard, or lava moat. The empty container is then carted back to the facility to be refilled and redeployed, completing another phoenix-like cycle of rebirth, flame, and burger. Each zip code has two service days per week, with unscheduled delivery available for an additional fee of $4.99.
