Office Depot and OfficeMax offers the Uni-Ball Signo 207 Retractable Fraud Prevention Gel Pens 4-Pack for $1. Opt for in-store pickup to avoid the $9.95 shipping fee. That's tied with our mention from six days ago and the lowest price we've seen. (It's the best deal today by $7.) It features assorted colors, each with a 0.7mm medium point.
