Walmart offers the Hyper Tough 106-Piece Rotary Tool Kit, model no. 6200, for $14.97. Opt for in-store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find by $11, although we saw it for $2 less in November. It includes a rotary tool, blow-mold case, and 104 accessories, including grinding stones, cut-off wheels, and sanding discs.
