Maybe try a Sam's Club they're owned by Walmart and carry different stuff!
I have not seen it in Walmart in the Placerville area. But keep in mind that with the change of seasons comes the change of products on the Shelf sometimes. Also every different store carries different items based on the location of the store and the demographic of the people who shop there so if you're looking for something that's a little bit more difficult to locate I would definitely start looking around areas that you think would be viable candidates for carrying the products I hope this helps.
