I went to Home Depot and did a propane cylinder exchange. The propane tank had a $2.50 rebate form from AmeriGas on it. The "customer message" on the reverse side of the rebate form explained that Amerigas is no longer putting 20 lbs of gas in a 20 lb tank, instead they are only putting in 15 lbs of gas.
With the weight of the tank, I believe this is deceptive as a consumer cannot tell whether the tank contains 20, 17 or 15 lbs of gas. Home Depot does not make its customers aware that they are only getting a 3/4 full tank. Amerigas tells you inside the "Important Customer Message" which is printed on white paper, folded up to 1" x 2" and attached to a white tank. The only place that they mention they are only putting in 15 lbs of gas in in the second paragraph of the "Customer Message" which has the rebate form on the reverse side. I would rather have a tank with more gas in it and be charged more than have my propane run out quicker.
I feel this is deceptive and dishonest.
