With everything else you’ve got going on for the next month, picking up teacher gifts may have been pushed to the back burner. But today, Amazon is giving you a golden (and silver, and purple, and green) opportunity to get that done with a major sale on markers, pens, and color sticks. You can never have too many Sharpies, and Paper Mate’s felt tip pens have something of a cult following among educators. You can even pick up some Mr. Sketch scented markers for the kids’ stockings while you’re at it.
