Woolies has the Oral-B Vitality Pro Rechargeable Toothbrush in Black for $30 this week, slashed from $69, that's $39 off without needing a loyalty hack or coupon. If you've been putting off switching from a manual brush, this is about as low as this model gets at a major supermarket. IGA also has it on special at $43.60 (down from $50), but Woolies wins the week by a long stretch. Grab it with the groceries and you won't need to think about it again.
