Anyone know any places to get supplies / blanks cheaper than the ones mentioned (mudhole, Janes,)

Might try this one:

I really don't know what the best place is yet. Just getting into it.

Thanks Bean I also am just starting

I too am fairly new to this hobby and so far I am not aware of any supplier that is substantially cheaper than another. What I have found is a few carry everything and the rest are hit & miss on selection. I played the price comparison game a couple of times and when going with all the lowest prices I was going to pay more due to shipping from all the different sources so I now try to do my business with one at a time.
A couple that I have not seen mentioned...
