The future of the on-demand economy is shaping up, and soon anything you might need or want, from toothpaste to kittens, could be delivered to you in a snap.

The future of the on-demand economy is shaping up, and soon anything you might need or want, from toothpaste to kittens, could be delivered to you in a snap. Grocery delivery app Instacart tapped into this “I want it now” mentality for some smart Halloween marketing: Seattle residents can use the app to order last-minute costumes that arrive in one hour. The startup conceived the campaign after receiving costume requests from many of their customers, and the service will be active until 8pm tonight. (Instacart)
