Are your jumps priced as pairs or each?
If an item is described as a "pair" then you are buying 2 pieces. Standards are "pairs"--you get two for the price. Brush Boxes, Vertical Walls, Jump Cups are "pairs"--two pieces that make one jump are included for the price. Gates, you get one gate. Cavalletti, one per price. The rule is that if it is called a pair you are buying two pieces.
