I have a friend with a business that sells chilli sauces. If I were to buy a pallet's worth he would give me a better price per bottle than if I bought a box of sauces.
We should have some ability to apply discounts based on pack size. If we take the following example where a box has 8 bottles and a pallet has 80, if someone were to order 100 bottles they would get the following :
80 at a pallet price
16 at the box price
4 at the individual price
