Amazon offers Prime members the Paper Mate InkJoy Ballpoint Pen 8-Pack
in Assorted Colors, model no. 1781564, for $2.99
with free shipping
. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping adds $6.27. Sam's Club
charges the same for its members.) That's the lowest total price we could find by $4, although we saw it for a buck less last August. Each pen features a retractable ballpoint, rubberized grip, and metal clip.
