Add min and max to product categories This post is outdated
I have customized products in my shop and I want the customers to pay only once for the customization, so if he wants to products the second one is a lot cheaper.
I have two categories now: Main and Second products. The products are identical but the "Second products" have no customization in it and are cheaper.
My question is: How can I tell Shopify that it requires EXACTLY one product of "Main products" to proceed with the order? So users won't be able to buy "Second products" cheaper without customization or buy two "Main products" for mistake and pay too much.
My approach was to work with the weight. "Main products" have a weight of 1 pound and "Second products" 0 and to make an order you need to have exactly 1 pound. Is there are a better way to solve this problem?
Thanks in advance.
