For Prime members only, Amazon offers the Bosch Impact Tough 32-Piece Screwdriver Bit Set for $12.98 with free shipping. (Lowe's has it for the same price with in-store pickup.) That's tied with our mention from a week ago and the lowest price we could find by $3. Each bit has laser-etched markings.

Update: Note that this item is temporarily out of stock, but can still be ordered at this price for delivery when available.

Update 2: It's now back in stock at Amazon for all customers, with free shipping via Prime.
