What is the best app or tool I can use to get an alert the second someone drops the price on an eBay listing I am watching? I have no idea what I am doing and I feel so stupid even asking this but I have been staring at this one specific listing for like three days straight. It is a used Fujifilm X-T30 camera and the seller has it for $700 which is way out of my budget but they have it listed as Buy It Now and I am just terrified someone else is gonna swoop in if they lower the price and I am not looking at my phone right then.

I only have about $500 saved up from my part-time job and I really need this before my brothers graduation in ten days because I promised I would take all the family photos for him. I tried looking at the eBay settings on my phone but everything is so confusing and there are like a million notification toggles and none of them seem to say tell me when this specific guy lowers his price by a hundred bucks. I tried searching the app store but there are so many options and I dont want to download something that is going to steal my password or just not work.

Is there like an outside app or a website that does this for free? I saw something about browser extensions too but I usually use my phone so I dont know if that helps. I keep hearing people talk about price trackers but I dont know if those are only for Amazon or if they work for eBay too since eBay is all individual sellers and stuff. I also saw something called sniping but I think that is only for the auctions where the timer counts down right? This one doesnt have a timer it just says Buy It Now.

I am literally refreshing the page like every ten minutes and it is driving me crazy because I am supposed to be in class right now but I cant stop checking. If there is a simple way to do this please explain it like I am five years old because I am really not tech savvy at all and I am panicking that I will miss out on the only good deal I have seen in weeks...
