Newbie question here. I got my Kneading Machine yesterday, and my extruder today....now I need some clay! How much should I be paying for fimo? I just did a search on amazon and through my Prime account can get it for $5.00 a pkg, but no shipping. Even with no shipping, that sounds high. Anyone have any favorite places to buy their clay online? I'm 100 miles from the nearest town where I can buy it, so online it has to be. Thanks!
