Comfyshoes- I wanted to add that it's not only department store's that hire personal shoppers.
Publix supermarkets are introducing a new shopping program for its customers. It is going to be called curbside pick up.
With this format a dedicated shopper at the store puts together the customers list of items that's available for pickup.
This is really to help those that are in a hurry and don't have time to go inside and shop for groceries. It hasn't started yet but it will in the future.
