It really depends on your circumstances. I know people making good money from it. I have also seen lots of others come and go. I find it difficult because I work ft and like to spend my "free" time with the boys, so I do the bare minimum of parties. So I don't make much money, but I get to buy what I want cheaply (and I do get a bit of extra spending money too). If you have the time and enjoy it, you could do really well at it.
