Why does it cost more to buy new fusion blades than buy new fusion razors? I've been using fusion blades a while, and I like them. I need new ones, but may have to change brands. Where can I get them cheaper?

Companies do that because they expect that you will use the same razor for a while but keep buying blades. Just think about it, if you charge more for the blades, it'll be more profitable.

I'm not to familiar with razors though because I usually use hair removal cream. It's just cleaner and it doesn't hurt. So I can't help you in finding another brand.
