I may have found a bug, or I am just not understanding how this works. I am trying to set up a quantity discount for mugs. I set it to 4 (I want customers to have a price of $14.00 per mug as opposed to $16.00 per mug if they buy a set of 4). When trying this, I get the $16.00 price for 1 mug, $14.00 price for 4 mugs, but I also get the $14.00 price for 3 mugs (I also tried other discount amounts and other amounts in cart with same results.) Am I setting this up wrong or is it a bug? See screen shots
