I think it all depends on what the yarn is that's wrapped around the cones. I bought a cone of Sugar and Cream once upon a time, and it's just the same.
If they're clear as to what the yarn is, then the way it's packaged shouldn't matter. Yes, they're probably but on cones for people who use it in bulk, but that doesn't mean that you can't use it for hand knitting, too.
