Amazon has announced a new perk for Prime members in the form of free same-day delivery from select retail stores. Prime members in or around Atlanta, Chicago, Dallas, Las Vegas, Miami, Phoenix, Scottsdale, Seattle, and Washington D.C. can now shop from Diesel, GNC, PacSun, and SuperDry through Amazon.com or the Amazon app. Shopping from Sur La Table and 100% Pure will also be available in the coming months. Only some of the participating stores are shoppable in each region at this time. You can see which stores are shoppable in each region here. Same-day delivery is free for Prime members when ordering $25 or more. Otherwise, there is a $2.99 flat fee per delivery for Prime members or $9.99 for non-members. Orders must be placed by 5 pm to receive your items by 10 pm the same day. These orders are packed by and picked up from the retail store itself, not Amazon workers or warehouses. You also have the option to order through Amazon and pick up the items at the store yourself in some cases, which is similar to Amazon’s arrangement with Best Buy for Fire TV Smart TVs.
