As before, Express is really about bringing a same-day choice to retailers where it wouldn't otherwise have the option, such as Costco, Fry's and PetSmart. You have to buy a minimum amount ($15 to $35), but you can pay a delivery fee (typically $5) instead of opting for the $95 annual membership. It's not quite an Amazon Prime competitor, but it does serve as a foil to Google's arch-rival. If you're like many shoppers, you skip search engines entirely in favor of store sites like Amazon -- this is Google's way of bringing you back to its home turf.
