Denver-based Choice Market is just what it sounds like. Customers have a choice in the way they interact with the store, and that choice is fueled by technology. Options include online and app ordering, delivery, traditional checkout and self-checkout.

Choice Markets’ second location opened in late 2019. It features fuel pumps, electric-vehicle supercharging, a bike-share terminal, electric-scooter charging stations and a solar canopy. The small chain partnered with Ava Retail, Redmond, Wash., to enable frictionless checkout, which uses artificial intelligence, computer vision and the internet of things to track customer purchases within the store.
