Colgate Keep Replaceable Head Toothbrush, Deep Clean Starter Kit, $3 (or cheaper w/ S&S)

Seems like a bit of a niche product but may appeal to some at this price. New low on CCC by a bunch. Subscribe and Save options are available to make it even cheaper (e.g. $2.55 @ 15%). Also stacks with “buy 5 to get 5% off.” Includes one handle and two brush heads.

• Replaceable head manual toothbrush for 80% less plastic compared to similarly sized Colgate toothbrushes
• Floss-tip bristles gently reach 4X deeper below the gum line and between teeth (this toothbrush does not replace flossing vs. an ordinary flat trim toothbrush)
• A grip that doesn’t slip for control while brushing
• Cleans teeth, tongue, cheeks and gums
• Long-lasting and lightweight aluminum handle
• Two toothbrush replacement heads
• Recyclable toothbrush handle and packaging
