Okay so I'm trying to buy some stuff for my new place because I just moved to Chicago and literally everything is so expensive here. I've been looking at some kitchen stuff on Amazon like an air fryer and a stand mixer but the prices keep changing every single day it's actually making me so stressed out. Someone told me there are things you can add to your computer to track the prices for you but I'm honestly so bad with technology and I'm scared of downloading something that will break my laptop or steal my info. I have like a $300 budget for everything and I really need to make sure I'm getting the actual best deal and not just some fake sale. I heard about one called keepa and another one with a weird name like camel something but I dont know which one is actually good or if they even work for real. I need something that:

• is totally free because I have no extra money right now
• is really easy to use because I get confused easily
• wont slow down my chrome browser
• tells me if a deal is actually a deal or just a trick

Does anyone know which one I should get or if there's a better one for someone who doesnt know what they're doing? Im trying to get this all sorted by next week before the big move...
