Hello, I'm designing a site for a client who delivers a food product herself (Doesn't ship anything), and therefore only delivers within a certain radius of her store. Does anyone know of a way to set this up? Best thing I have figured out so far is to upgrade the business plan subscription to be able to limit to specific area codes. She also needs to take orders at least 2 days in advance of fulfilling the orders. I created a custom form for customers to enter the date they would like their delivery, but I'm wondering if there is a way to not accept orders if they try to order for same day delivery. Any advice is greatly appreciated. Thank you!
