Their is a thing of course called impulse buying. Basically buying something because you can. I go through this a lot I’m afraid. I have a lot of movies for some bizarre reason. Lots of books to that I probably don’t need. Thankfully I’ve gotten better at impulse control so that I don’t end up needlessly buying things. All it really is is just telling yourself that you don’t NEED it, you might WANT it but you don’t need it. It’s good that I do or else I’m relatively sure that I’d be broke.
