Rural King review: wood fuel blocks

Put a "ton" of wood fuel blocks on layaway in july 2015. was to be called by october 17 to pick it up. no call. i called oct. 21 and finally tracked it down, but the man i finally talked to said "no one else wanted to take the call". picked it up to find it was 50 38 pound bags = 1900 pounds. short 100 lbs. (a ton = 2000 pounds). newspaper ad said $3.99 by the ton pre-booking. my receipt says $3.99 by the ton. my packing slip says $3.99 by the ton. i inquired and was basically told you got a good deal it was on sale. they never denied it says a ton. if every "ton" sold by what 84 stores was short 100 pounds (5%), how much did they rip everyone off for? enough for a class action suit?
