I usually pay 8 EUR for mine. It's natural and carries all those fancy names such as vegan, cruelty free, and many other 'free' things :D I would pay 10 or even more if I'd know that it would work for my sensitive skin. I once had a home made deo from a friend and it wasn't good as it made my skin too dry and kind of flaky.

PS: I wouldn't use a deo with beeswax in this since I don't use any animal products.
