Canon rebel T7 camera with all accessories included

I’m only selling this camera because I just don’t use it. I got it about a year and a half ago off of Amazon and paid $600 for it. I’ve only used it a handful of time but now the last two times that I have used it I have realized there is a little spot in pictures that only have very light backgrounds. Apparently there is an easy way to fix this but I know anything about cameras and since I don’t use this enough, I’m just gonna sell it.

It comes with the tripod, comes with the battery,battery charger, wide angle lenses a filter kit a slave flash, the carrying case basically it’s the whole kitten caboodle
Honestly, I have no idea what price it should be! Don’t be afraid please just message me or make me an offer that I can’t refuse!!!
The camera works perfectly. The only thing that I can’t figure out is the little spot that shows up in certain pictures usually you can’t even see it. And like I said, there is a way to fix it but I have no idea if it just needs to be cleaned or what!
