Instacart is an online grocery delivery service that has more in common with Doordash or Postmates than Amazon Fresh. Unlike grocery stores that deliver their own goods, Instacart works with thousands of personal shoppers who will go to the store of your choice, buy everything on your shopping list, and deliver it right to your doorstep. You can place orders through their website or a convenient app, select from a wide variety of stores, and choose to pay per delivery or opt for a yearly subscription fee. Here's how Instacart delivery works.
Instacart is totally legitimate. It may seem out of the ordinary to have a stranger go grocery shopping for you, but Instacart is a real business with a long track record of providing a valuable service. Whether or not Instacart is worth it is an individual matter. The per-delivery fee is fairly low, so it can represent a real value if you're too busy to go grocery shopping yourself. Prices can be more expensive than you would pay in-store though, so it's really a question of whether or not you feel like it's worth paying for the convenience.
Instacart is a lot like any other online shopping experience. You make an account, choose the items you want to buy, and then provide some type of payment. The only difference is behind the scenes, because Instacart doesn't own any grocery warehouses or stores. Instead of building that kind of infrastructure, Instacart pays personal shoppers to go to the store of your choice, buy the items you request, and then deliver the entire order straight to your door. Here's what the process of buying from Instacart looks like:
