If your household has children, then you know how expensive summers can be. When the kids come home from school, households with kids can suddenly find their grocery bills increase significantly when the kids are home for all three meals. Even if your household doesn’t have children, rising grocery prices can put a pinch on anyone’s budget. Luckily, America’s largest retailer Walmart is launching new online grocery promotions that make grocery shopping cheaper and more convenient than ever.

Walmart’s new online grocery promotions are drawing in new customers to this brand new way of shopping for affordable foods. Just like shopping for any other items online, Walmart’s online grocery shopping is a great way to avoid the crowds and lines of in-store shopping and save you time. Nearly all of the popular brands and exclusive deals offered in Walmart’s brick-and-mortar grocery stores are available online, and Walmart recently expanded their online grocery delivery to cover major metro areas which include more than 40% of all U.S. households. Luckily, the greater Houston area is one such location.

“We’re saving customers time by leveraging new technology, and connecting all the parts of our business into a single seamless shopping experience: great stores, easy pickup, fast delivery, and apps and websites that are simple to use,” says Walmart president and CEO Greg Foran. “We’re serving our customers in ways that no one else can. Using our size and scale, we’re bringing the best of Walmart to customers across the country.”

To promote their new grocery services, Walmart is offering  first-time online grocery shoppers promo codes which can save them up to $10 on their first online pickup order, while all first-time online delivery shoppers can get free delivery on their first order over $50.

For online grocery pickup, use the promo code WOWFRESH for $10 off. For online grocery delivery, use the promo code FRESHCAR to get free delivery on orders of $50.
