 which is a quick and easy way to do it for sure. But what a lot of people don't know is we can actually refill your existing propane tanks as well. And it will save you about 10 bucks versus doing an exchange. But my favorite part about refilling your tank versus exchanging it is you don't have to wait until it's empty. You can just bring it by for a top off when it feels like you're getting low. And as my grandpa Bernie used to say, it's just as easy to keep the top half full as the bottom.
