If you’re going into battle with a giant like Amazon, you need to show up with a solid game plan—even if you’re a ubiquitous household name like Walmart. CNBC reported that the “Always low prices” superstore just announced plans to expand its online grocery-delivery offerings to about 800 stores in 100 metropolitan areas this year, just a few weeks following Amazon’s news of adding two new cities to its grocery-delivery service. (Coincidence? I think not.)

Following the expansion, more than 40 percent of shoppers in the country will have access to same-day delivery on a wide selection of groceries, according to CNBC.

Following the expansion, more than 40 percent of households in the country will have access to Walmart’s same-day delivery on a wide selection of groceries (making it much easier to satisfy those spontaneous avocado cravings), according to CNBC. Several businesses, including Uber (which will help deliver the grocery hauls to homes), have joined Walmart in its ongoing efforts to compete with Amazon in the ever-growing market for commodifying convenience.

To order your groceries from your local Walmart, simply log in to Walmart’s website or the app, fill your basket with at least $30 worth of goods, and pay a flat-rate delivery fee of $10. And you don’t need a subscription, as most similar services require. Plus, you get $10 off your first order of $50 and free shipping. Sounds pretty, ahem, prime—right? Better watch your back, Prime Now.
