Users can order from a variety of online retailers including CostCo, Whole Foods, PetSmart through Express' single UI, then receive their orders two days later (or same day if you pay extra). It's structurally quite similar to Amazon Prime except you're able to order from a bunch of different retailers rather than a monolithic fulfilment center. Additionally, customers in New York can choose between the standard $95 per year subscription model or opt for a $5-plus per order, pay-as-you go system.
