An icon without a label is inexcusable. I can hardly believe this one, it’s such a blatantly awful mistake, and such an easy one to fix. See these icons?
They’re lovely images, actually, but I have no idea what they mean because they lack tooltips on hover. So, cart. Someone’s going to buy it? Someone’s already bought it? What? I never quite figured that one out. Dollar sign is easy enough: Money has been exchanged. The box? Shipped? Received? Nope: it means “Shipping label printed.” Star with a pencil? Write something? Written something? At least the next one, the star with an envelope gives some clue. They’re “Feedback left” and “Feedback received.”
Why did I have to think about that? It’s not the user’s job to figure out your iconography, certainly on a web page, where fixing the problem involves nothing more than adding title="This picture means this thing" to the link tag. Epic fail.
