Do they sell clay.

They do but it usually runs out quick. They don't know when they get them in stock so You're lucky if you get it. No you cannot tell them to put some on hold, it's first come first served

Try right after they recieve thier truck, Mondays for the store in Anaheim.

They had the potato starch clay last weekend.

Yes They do. Plenty👍😀they run out Rapidly..

I've never seen it sold there
