Lowe's offers the DeWalt 68-Piece Screwdriver Bit Set for $19.98. Plus MyLowe's members bag free shipping. (Not a MyLowe's member? It's free to join.) That's $10 off list and the lowest price we could find, although we saw it for a buck less a week ago. It features the most common geometries of 1" and 2" screwdriver bits.
