I don't know if they were THE best price, but
www.atoygarden.com had the stockmar crayons on sale, and I had to get some other things from there as well, so I went ahead and got them.
I got the block crayons, as well as the Ferby pencils (interesting about the proper way to hold them...I'll 1st wait and see if DS is interested) plus blackboard chalk and the glass crayons. My parents are getting him an easel, and we have lots of paper around that we recycle. I am going to wait on paints for a while yet, see ho DS does with this stuff.
