Walmart's never-ending quest to beat Amazon has it venturing into unfamiliar territory: meal kits. The big-box retailer has started selling just shy of 30 meal kits (such as a Thai crab curry) from multiple brands. How much you'll pay varies, but it's not uncommon to pay $35 for a meal for four. There are also bundles, such as a $60 Everyday Supper pack that serves three meals for two people. The brands themselves fulfill the orders. This isn't a subscription service like Blue Apron, but it's helpful if you'd like a fanciful meal without hunting down ingredients. And importantly, Walmart will soon compete more directly with Amazon's meal kits through an app tie-in.
