I was trying out Instacart a few days ago and thinking whether I should purchase their Express program. This is what I realized: - You pay them $150 a year. - On every order, they add a 10% service fee that helps them keep the service running. This is optional, but you have to remove it every time. - The delivery guy expects his tip. I am wondering if this is cost-effective this way or not.
