I don't think it is raw, but you can buy "100% cacao" at Walmart. It's baking chocolate in the form of a candy bar. On the front it will say "100% cacao" and on the ingredients it will say "chocolate" as the only ingredient. I do eat this sometimes because raw cacao beans are outrageously expensive where I live, and it's really cheap - a large 8 oz bar for about $2. I just break off a chunk and chew it with some raisins or honey. Otherwise I don't eat regular chocolate because of all the sugar and other crap they put in it.

Baking chocolate has the natural fat (cacao butter?) left in and has no sugar. You can also get Hershey's cacao powder that has had the fat removed.

I don't know how many antioxidants are left after raw cacao beans have been processed into baking chocolate or powder, but Hershey's does put a little antioxidant doo-hickey on the label so there must be some left.
