CnBirdsFly via eBay offers this Mini Screwdriver Keychain Set in Black or Silver for $1.98 with free shipping. That's tied with our mention from a week ago and the lowest total price we could find by $2, outside of other eBay sellers. It features one Phillips and one flat-head stainless steel screwdriver.

Note: This item ships from mainland China and should arrive in three to eight weeks.
