I have had them before but my mom used to pay for them for me. I have a part time job and pay for most of my things now. I can afford it, but it would make money for other things shorter. I mainly want them because my nails are short and fragile, but I also know that getting them might make them worse. Is it worth paying like $40 twice a month for them?
Personally, I don't think so. It's not like quality clothes or a fantastic hair cut that will stick with you for awhile. They only last two weeks and plain old painted (and unpainted) fingernails look fine on their own.
Nope, don't do it. If you are on a strict budget, only budget for the things that you NEED. Go through companies like Groupon and livingsocial if you want to do those things. At least you can get them really cheap!
