… today may just be the day to pull the trigger.

As part of their Deals of the Day, today Best Buy is offering various colors of the Sonicare Series 2 Rechargeable for just $39.99, and then if you apply coupon code TWOSERIES10, you’ll save another $10. Shipping is free, or you can pick up at your local store if you want it faster.

For comparison: The same model is averaging a 4.5-star rating with over 4,500 reviews at Amazon, where the price is also currently $39.99, but without that extra coupon.

I bought electric toothbrushes for my teens just so I could stop wondering if they were doing a good job brushing. Totally worth it.
