For a product with a fixed price, how can I add a monthly maintenance subscription, so it is automatically added to the customer’s cart? Currently I have them set up as 2 separate products (1) website design (2) monthly maintenance subscription. The maintenance is required when purchasing the website design, so I would like if I can add a subscription line to the product. I can’t use the Pricing Plans because It’s already being used for another set of products (Wix only allows 1).
Or can 2 products be linked together so that when one is purchased, the cart will not accept payment until the missing item is added to the cart?
If this can be done through Code, I’m good with doing that.
