WEST DES MOINES, Iowa — Hy-Vee Inc. said it has expanded its Aisles Online grocery e-commerce service to all 240 of its stores in eight states following a successful pilot of the program.

Through the service, customers can order and pay for their groceries online and either pick them up at a store or have them delivered.

“Hy-Vee is committed to providing customers with the best value, the greatest convenience and the most choice in their shopping experience,” said Jeremy Gosch, senior vice president of merchandising at Hy-Vee.

“Hy-Vee Aisles Online is tailored to fit our customers’ needs and their families’ busy schedules,” he added. “We still love seeing our customers in the store, but we believe this is a value-added service for customers during those times when they can’t make it to the store or are pressed for time.”

Customers can use their hy-vee.com account to select their preferred store before shopping that store’s inventory.

Customers also can create shopping lists and mark products as their favorites. When customers link their account to their Hy-Vee Fuel Saver + Perks card, their most recently purchased items will automatically be listed first, creating a seamless shopping experience, the company said in a statement in December.

Once customers place an order, an Aisles Online personal shopper hand-selects the products, which ensures the orders are fresh and accurate, Hy-Vee said. The groceries are kept in climate-controlled totes until they are unloaded into the customer’s vehicle or delivered to the customer’s home.

Store pickup and home delivery are both free for orders worth $100 or more, the company said. For orders under $100, shoppers pay $2.95 for pickup and $4.95 for delivery.

“Our customers have been asking for an easy and convenient online shopping experience, and we’re happy to be able to offer that to them,” Gosch said. “We’re very proud of this new service and how it’s been received.”

Hy-Vee introduced the Aisles Online program to selected stores in the Des Moines metro area in April and steadily extended the service over the summer to other locales.
