Amazon offers Prime members the Pentel EnerGel EnerGel Deluxe RTX Metal Tip Pen 6-Pack, model no. BL77BP6M, in Assorted Colors for $5. Clip the 15% off coupon to cut the price to $4.25. Plus, Prime members receive free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $6.32.) That's tied with yesterday's expired mention as the best price we've seen. (It's around a buck under what you'd pay in local stores.) These pens feature quick-drying ink, 0.7mm tips, and latex-free grips.
