Is there an alternative for Bob Ross paint?

I got a bunch of DVD’s from Bob Ross for my birthday and I would love to use them and learn how to paint for my own fun. Except… I live in Belgium and Bob Ross paint is nowhere to be found or you have to pay loads of money for it. Sinds I am a beginner, and I first wanna try if I like to paint, is there a cheaper alternative for his oil paint and liquid white paint that I can use and that is easely found?
