The service aims to challenge Amazon, and in particular Amazon Prime Now, the online retailer’s same-day delivery service that’s live in major cities around the U.S. for Amazon Prime customers.
What makes Google Express different is its retailer lineup. In most cases, it’s partnering with national retailers who either haven’t yet figured out e-commerce, or only offer delivery through more traditional means – not one-day delivery.
While the retailers will vary by region, some of the brands working with Google include Costco, Whole Foods, Kohl’s, PetSmart, Sur La Table, Fry’s, Road Runner Sports, Walgreens, L’Occitane, Payless ShoeSource, and Guitar Center.
Customers can either pay for a $10 monthly membership and receive free delivery when the order meets the per-store minimum ($15 in most cases, but some require an order of at least $35), or pay each time you shop starting at $4.99 per store. New members can try the service for 6 months free.
I've checked and it is working in most Greenville area zip codes. I'm sure the area is larger than that, I just didn't want to keep typing in zip codes! Check to see if you are in the delivery area:
