Groswift
Groswift is a mobile-app-based shipping network that lets you shop for groceries from the comfort of your home. You simply place your order on the app and one of our crowd-sourced local shoppers buys & delivers your groceries to your location.
I know you said you had to pickup the groceries after work, but I really need you to stay for a few more hours. Why don't you just use Groswift to get them delivered?
