Block of the month

I was at JoAnn's today and they have 2 block of the month quilts. I didn't
care that much for either one of them, but it got me to wondering. I think
this would be a good learning tool for me as far as technique, color choices
and patterns go.

Are there any online places that anybody is familiar with that would offer
Block of the Month kits? I would prefer not to be able to buy them all at
once, but would like to buy a kit a month and have to finish that one before
getting the next one. I am slowly learning to discipline myself as far as
buying stuff and then not using it.
