Walmart offers the Westcott iPoint Evolution Titanium Bonded Pencil Sharpener in Black for $10.04. Opt for in-store pickup to dodge the $5.99 shipping fee. (Amazon charges the same.) That's the lowest price we could find by $4. It features auto stop and titanium bonded blades.

Update: It's now out of stock at Walmart; however, Amazon still offers it for $10.04 with free shipping for Prime members.
