GrabMe is designed around the idea that people already at or near the places we need things from can buy and deliver them for us. So if there isn’t anyone nearby, we don’t ask users to go out of there way to get it.
However, GrabMe is new, so chances are there are plenty of people who are nearby and would love to grab what you need for a little coin. It only takes one person in your area willing to deliver. If you have a friend nearby who you think would be happy to delivery for you, invite them!
