I am looking to start a site now that provides food deliveries to people who are isolating now. I will have up to 5 different vendors. A customer can purchase products from any of the 5 (the product listing pages will be separated so one listing page per vendor), and checkout only once but they may order and have their orders fulfilled from different vendors. To make it worthwhile for each vendor they will all want different minimum order values.
So if a customer buys products from vendor 1 and vendor 3, and vendor 1's minimum order value is £10 and Vendors 3 is £15 i want to ensure that the basket has validation to ensure this.
Any help appreciated.
