ok so in my case I list my items imagine wood screws 25mm x 3mm I sell them in 1, 5, 25, box
these are my variations, when the item is sold I need it to deduct the correct qty from the stock qty, so I sell a box the qty should drop by 100 ,
i would also like to use these items in other products like making an kit that has 4 brackets and 20 screws
