Texas grocery giant H-E-B has announced a formal agreement with San Francisco-based Instacart — a grocery delivery service whose personal shoppers hand pick and deliver items from local stores — in Houston and Austin, as well as expanding the service to stores in The Woodlands and Katy.

Instacart already provides service from H-E-B under an informal partnership, but the new agreement solidifies the arrangement and gives users the ability to shop for virtually any product offered at the store, according to the Houston Business Journal.

"Don't have time to come to H-E-B? No problem. We'll bring H-E-B to you with Instacart," said Scott McClelland, president of H-E-B Houston Division, in a press release. "Instacart's ability to deliver on-demand clearly matches our focus of making our customers' lives better. We are excited to offer a larger assortment of H-E-B items to customers in Austin and Houston."

Instacart initially launched in Houston last August and Austin last May. In Houston, customers currently have access to items from Whole Foods Market, Costco — no membership is required — and Petco, in addition to H-E-B. Customers who utilize the service can expect items to be delivered in as little as an hour.

The service, which can be accessed through a phone app or online, is currently available in areas including River Oaks, Bellaire, West University and Memorial, with Katy and The Woodlands as the newest destinations.

New customers can open an account online and receive free delivery and $10 off their first order using promo code HEBLOVE through September 30. Instacart also offers Instacart Express — an annual membership that eliminates delivery fees for all orders of $35 or more — for a fee of $99 per year.
