For those who haven't joined Ibotta yet, it is, as a character in an 80s French movie would say, super cool.
Ibotta is a shopping rebate site for grocery stores. You go in to the supermarket (or drugstore or place like that) and buy stuff like you normally would. Then, you look in your Ibotta app (I do the looking afterward so that I don't get tempted to buy stuff.) and, if the item is there, you take a picture of your receipt and they give you money back. Usually, it's for branded stuff, but occasionally it's for produce, milk, etc.
Best of all, if you sign up for Ibotta through my link you get $10. I also get something if you do something (I'm not sure what either something is, but that's my link, anyway.).
Remember, Ibotta = "Buy stuff that you would have bought anyway but get stuff back afterwards."
