Here's how the deal works:
Buy the Oral B Professional brush here for $37
- get free Crest whitestrips and coupons (as pictured)
- submit for $20 mail in rebate
- pay around $3 shipping
- Net cost ~$20!
It's like paying $20 for a $75 power toothbrush and getting $30+ in free Crest Whitestrips! Not bad!
