That's the advantage of an experienced expert. They know!
The only times I've bought anything called "potting mix" from my HD, it was so heavy I wouldn't put it in a raised without amending it.
But I read that the big-name companies put different things into the same product, in different regions. They use what's cheap locally, and don;t ship it very far. So YMMV.
(I buy bark from Lowes and hardware from HD.)
