Or actually, products by weight. I will be offering products packaged on order in different specified sizes and want the stock to math.
For example: I have 10 kilos of a product in stock and want to allow costumers to order 10 1 kilo bags or 20 500 g bags, but not both, and the stock to get updated accordingly.
I guess I would need to make the smallest product the "main" product and the others packages with several of it.
Anyone who has any ideas about what plugin to choose? Ideally, I would like the sizes to be variations on the same product page.
