Hi Sarah,
I used to order my HT blocks from a site called The Crafty Rat, and they had decent shipping prices and I got my blocks fast. I live in Washington State. I think they are in California, but I think I remember that the shipping was flat rate so it probably does not matter what state you are in. You could try that site, and I remember Breyer saying she gets hers from the Rat Shack website? I am sure there are other members on the forum who will have even more suggestions!
