I haven't ordered anything from Habor Freight online before, so I can't say anything about their shipping department. But a few years ago I bought their rotary blades, the same ones you are describing, and I was not impressed. The blades were skipping continually and were so dull. They weren't worth even the couple of dollars I spent. Maybe I just got a really bad pack, but I personally won't bother with them again. Just my experience.
