Has anyone ever donated plasma? Experiences?

So Christmas is coming up and I wanna buy my boyfriend a really nice gift but I’m broke and have no way of getting a job since I’m always dancing (I’m 18 and a senior in high school) I’m considering donating plasma (the place that does it is called Biolife) because they pay you each time you donate and that sounds like an easy way to get money but I was wondering if anyone has done it before? And if yes, have you experienced any bad side effects or anything?
