Brad's Deals Editor Marisa,
This 12-Pack of Colgate Premier Clean Toothbrushes is $6.34 at Amazon. Even though it doesn't show a price drop, this is the best deal you can get on a 12-pack of toothbrushes right now. They're usually around $1 per toothbrush at other sites, but here they're $0.53 each. If you want 24 toothbrushes, you can check out this deal, where they come out to $0.44 per toothbrush. Prime members get free shipping. Non-members get free shipping at $25, otherwise it adds $5.99. Sales tax is charged in most states.
