I need a module or addition to Prestashop 18.104.22.168 that allows me to do the following on a PER PRODUCT basis.
I need to be able to specify an amount for each product in stock quantity terms that allows you to sell as multiples.
For example. If I am selling Bunches of Flowers, I want to be able to sell them per flower and specify how many flowers are in each bunch. So if the price is $1 per flower, and I specify there are 13 flowers in a bunch, the customer may not order 12 or 14 for example, but he can only order multiples of 13. This must then add 13 items to the cart and remove 13 items from stock levels etc.
