Head on over Arm and Hammer and check out their special promotions! Print these HIGH VALUE coupons:
$2.00 of arm and hammer spinbrush electric toothrush
$4.00 off coupon for arm and hammer sonic recharge spinbrush
I think these would be a neat stocking stuffer and you could probably snag one up for under $5 after the $2 coupon, since they retail for $7-$6 depending on the store.
We have the thomas and friends spinbrush (pictured above) and so far have been very happy with it! My son likes it so much he always reminds me we need to brush his teeth
