Amazon announced it’s adding a select group of brick-and-mortar retail brands to its same-day delivery service for Prime members from PacSun, Diesel and Superdry, as well as vitamin retailer GNC, in ten U.S. cities.

The service is free for Prime members when they spend $25 or more, or $2.99 if they spend less than $25.

The cities include Atlanta, Chicago, Dallas, Las Vegas, Miami, Phoenix, Scottsdale, Seattle, and Washington D.C. Additional retailers joining the service in upcoming months include Sur La Table and 100% Pure.

Under the set-up, Prime members in eligible zip codes visit the Amazon app or, browse the curated selection from retail stores in their area, and select same-day delivery. Amazon sends the order to the store, the retail store fills it from its inventory and an Amazon delivery partner picks up the order and delivers it to customers as soon as that day.

“We see high potential in our expanded seller partnership with Amazon, which includes delivery directly from select PacSun retail locations,” said Mimi Ruiz, vice president of e-commerce, PacSun.

“The expansion of Amazon’s same-day delivery to include beloved brands delivered directly from nearby retail locations is just another way we are offering customers even greater selection, at faster speeds,” said Sarah Mathew, director, Amazon Delivery Experience. “We are excited to see this new model come to life and look forward to adding more brands, stores and locations to the program.”
