Have you ever tried Swagbucks? You do surveys, watch ads, do various little tasks and use their search engine and you can make some money. I've made $25-$50 a month when I was really motivated at it; some people make more. You can cash out for gift cards (including amazon) or paypal. It has helped me when things were rough. It's not exactly fun but it doesn't take too much time unless you want it to.

I hope you find a way to make the $50 less painful. I'm dreading having medical bills if I ever get these scopes done. I've had dental work on carecredit forever but otherwise just was paying my co-pay for my pdoc. Now that will go up. My hospital is more reasonable than yours though. I'm sorry yours don't know they are dealing with humans.
