Pros
Immediate pay: If you have an unexpected or astronomical bill that needs paying off and your regular check won't cut it, this is GREAT for that. Most of the time will be spent in your car listening to your music.
Cons
Instacart itself pays crap. They nickel and dime the customers, so it LOOKS like all those surcharges and fees are for the delivery service, but it's not. It's to line Instacart's pockets. You will jump through hoops of fire before speaking to a live person in Care, and when you DO get to talk to an actual person, 9/10 times English isn't their first language. Every expense is on you. Gas, repairs, your lunch, the XL Sharpie you bought to mark bags with, ALL of it comes out of your pocket. Even the insulated bags they want you to have before starting. Unless you're okay with getting your butt handed to you during tax season, keep track of every single expense. That Sharpie, your lunch, the appropriate percentage of your phone bill and electric bill to CHARGE said phone, gas receipts, repair costs, the whole 9 - keep EVERY receipt, cause tax season will eat you alive. If you're in the boonies and they don't tip well, you're SOL my friend, unless you'd like to drive further out to where they DO tip. Accept the fact that this job WILL destroy your car. There's no getting around it.
