Being addicted to online shopping is actually a thing, and it's just the worst because you just keep spending money non-stop until you finally end up homeless on the streets because you spent everything you have on pointless things.
The thing is, people spend money when they go out, so if they decide to stop spending money they'll just avoid malls or any place where you spend money, but with the internet everything is always in front of you and in case you were able to successfully stay away from those websites they will follow you everywhere you go by showing up on ads, either on Facebook, or pretty much any website, you just can't escape it.
