As a former customer and employee all i can say is "just say no" to amerigas. They have scamming and lying down to a new art form.
Their "employee pricing" was often higher than the local competition. The management has no cares for the workers or customers all that matters is the bottom line. The last three years we were told they werent making and a 1% raise if any would be it, then the last two years we were cut back to 36 hours a week for six months. At the beginning of this year they announced the purchase of Heritage Propane for a outrageuos sum.
The best plan is to support your local mom and pops cause Amerigas is buying out all competition it can to make you have to accept their services. As for the $100 tank pick up, the only time my former district charged it was if your tank was over 5% cause DOT will not let you haul a tank with more than that. Amerigas has more forms to fill out than the IRS so make sure you get a copy of everything you sign! As for those people with tanks in your yard for a couple weeks good luck.
I have loaded tanks sitting there for three and a half years! Best advice threaten to start charging storage fees.
