JUSTO is the new Amazon Mexico Fresh Grocery Food Delivery. It's sort of set up like Amazon Fresh. No prime membership needed. You can use your credit cards from your country and just put a Mexico address down and they will deliver now or later at your requested time frame. I always use the regular Amazon delivery but noticed the new option today since I've been away for a couple of months. You just go into Amazon Mexico and find the section for groceries. You can still order non-perishable foods through their regular site and have delivery in a few days.
