Instacart, the technology-driven, nationwide on-demand grocery delivery service, and Wegmans Food Markets will expand same-day grocery delivery service to Rochester, Buffalo, and Syracuse in August.

The service allows Wegmans customers to complete their grocery shopping online, and have their orders delivered to their doors in as little as an hour.

Wegmans customers will be able to fill their virtual carts with all their favorite products, from produce, meat, seafood, and frozen foods, to a wide selection of specialty cheeses, bakery desserts, packaged prepared foods and Wegmans’ line of chef-developed EZ Meals, by visiting instacart.wegmans.com or downloading the Instacart App. At check out, customers can add their Wegmans Shoppers Club number to receive available discounts, and choose a delivery window within one hour, two hours, or up to seven days in advance. Instacart’s shoppers will do the rest.

The same-day delivery service will launch in Buffalo-area stores on Aug. 1, Rochester-area stores on Aug. 8, and Syracuse-area stores on August 15. Starting on the date of launch, customers can visit instacart.wegmans.com and enter their zip code to determine if they are within the Wegmans delivery area.

Instacart waives the delivery fee on new customers’ first orders. After that, delivery starts at just $5.99 on orders of $35 or more. Orders under $35 will be charged a $7.99 delivery fee. All orders must be a minimum of $10.

A spokesperson with Instacart says that delivery rates do not increase for large orders, nor are delivery fees adjusted based on the number of items ordered.

Instacart Express membership is also available, enabling unlimited free one-hour deliveries on orders over $35 for an annual fee. After a free trial period, the annual fee varies by location from $99 to $149.

In addition, Wegmans adds a price increase to items to cover the cost of having a personal shopper pick, check-out, and pack the items on an order.

Taira Perrault said she’s excited to use the service in Rochester.

“It’s like wanting pizza delivered to your house, but you get Wegmans pizza and Wegmans groceries; fresh groceries.”

Others said they aren’t sure how they feel about it.

“I’m a very in-person type of person. I like to grab and hold the items, because sometimes online (I know from experience) my order doesn’t always come the way I envisioned it,” Susan Lim said.

Wegmans did say, through their Twitter account, that products excluded from Instacart deliveries include subs, pizza, alcohol, and hot and cold food bar items.
