I don't have to remember to be sure I have enough gas. The courteous, friendly folks in the office call with a reminder every fall, making me aware of any specials, and send me notices of sales in the spring. They give me a time frame in which to expect my delivery.
Then, the people who deliver the gas have the same customer service skills as the office folk. They come withing the estimated delivery dates. They answer any questions I have and provide me with a ticket showing how much gas was delivered so I can budget a reasonably close amount for my bill.
I've used Amerigas for several years. When I ordered 100 gallons it was 3.00 per gallon which I thought was pretty high. I am very disappointed in the price especially when I called around to other local companies and they were at least 1.00 cheaper.
