As one of its daily deals, TigerDirect offers the Canless Air System O2 Hurricane Computer Duster, model no. CA-202, bundled with the Canless Air System 3-Piece Attachment System for $79.99 plus around $4 for shipping. That's the lowest total price we could find for this canless duster by $16, although we saw the duster without the attachment kit for $4 less in September. This cordless electronic air duster is a longterm alternative for cans of compressed gas. The accessories kit features a flexible extension, cleaning brush, and tapered nozzle. Deal ends today.
