Cynch is a new home delivery service powered by AmeriGas. They will deliver 15lb propane grill tank (exchange) to your front door for $20, but if you use code: GRILLING10 you get your first delivery for $10. Follow the link below to order:
It's limited delivery area right now, but it's available in my area (Bay Area).
Even at $19.99 regular price it's still a pretty good consider you don't have to lug around a tank.
How it works:
Check your address
Select your tank; exchange ($19.99) or new ($49.99)
Schedule delivery (Tuesday or Friday in my area)
Leave your tank outside by 7am the morning of delivery
They drop off the filled tank and pickup your empty tank
That's it! You don't even need to be home
I just ordered my first exchange for $10 bucks. It was pretty easy.
From their site:
Can I exchange a tank from another provider (e.g. Blue Rhino)?
Yes, it just has to be any standard grill-sized tank in good working condition. If you don't have an empty tank to exchange, you'll need to order a spare tank from us.
