Some products are bought and sold by the kit — HGH usually is. On a product, set how many units are in a kit, and two things happen.
Entering quantity gets +1 kit and +½ kit buttons, so three kits is two taps instead of thirty. The line underneath tells you what you have entered in kit terms — "3 kits", "2½ kits", "1 kit + 3".
And each price shows what a whole kit costs at that tier, which is the number a buyer of HGH is usually quoted.
Stock is still counted in single units everywhere, on purpose. A kit is not the same size at every supplier — your vendor price book already records a different kit size per quote — so the unit is the only count the maths can trust. Kits are a faster way to enter and read that number, never a second one.
