lol (Plus shipping and handling USD 1,500.00) you must be kidding ..i shipped a 700lb four wheeler freight for a couple hundred bucks and your only shipping 120lbs
EDIT:
also i see you say "shipped via USPS Priority Mail and rates are calculated based upon weight" and that is bull i just added 10 Boilers to my shopping cart and shipping stayed the same so it seems your just charging an inflaited flat rate fee to make more money..
