A popular deal in the past, this toothbrush is now $99 again at Shavershop, both in store and on-line. I just picked one up today in Melbourne.
Not sure on the end date - but possibly around Mother's Day. Not sure how it compares to Oral-B (the heads are more expensive, but generics are available - not sure on their performance though), but I've had these recommended to me by family and friends.
Wife got me this toothbrush for Xmas. A huge jump up from the Oral-B 3000 (i think) I was using. A whole different level, would never go back.
