A long time ago, when you had to refill the propane or LP cylinder on your barbecue grill, you had to disconnect the hose, then struggle to heave the empty, albeit generally greasy, cylinder into your car and hightail it over to the nearest U-haul for a refill. Today, the LP exchange center has all but eliminated the need for a refill of your propane tank. But is that a good thing?

Let’s look at some of the pros and cons of the exchange program:

You can’t beat the convenience. The number of exchange locations is every increasing; you can find them at local DIY or garden centers, gas stations, supermarkets, convenience stores and even drug stores. With many of those open 24/7, you never have to wait until daybreak to get a refill if you’re one of those midnight barbecuers. PRO

You may not always get back what you give. Say you’ve got a fairly new, undented, clean propane tank for exchange. Do you really think you’re going to get one back in the same condition? Not in a million exchanges. CON

The cost varies. It’s usually cheaper to refill your tank than to exchange it. And when you refill, you pay for exactly what you take. Many exchange centers (including the big chain) are under-filling their tanks, meaning that you’re paying more and getting less. CON

Some offer home delivery. A couple of places will actually bring the LP right to your front door or your barbecue grill, as it were, and refill it on the spot. Almost as good as pizza delivery! PRO
