If you want to place an online order for, say, quail eggs, whole milk and fresh kale and have it delivered to your door the next day, RelayFoods.com is about your only option in Richmond. The online purveyor of groceries is actively trying to introduce the city to its website, which contains a vast catalog of standard grocery-store fare and local offerings from nearby farmers and specialty shops. There’s a surcharge to have the items delivered to your door, but for no charge you can pick up your stuff at one of a dozen drop points across the city.
