I've been meaning to do this a while & I found a rare MIR on it, so I went for it.

Older SONICARE Healthy White electric rechargeable toothbrushes, model R710, are clearanced. I've seen them in several stores in NW GA. Originally $109.99, now $54.99. Apparently, there's "newer" model out with a model number of R732.

There's a MIR from Delta Dental up to $15 ($10 for the toothbrush on select models including Healthy White, Flex Care, and Essense, and $5 for the replacement brushheads). Form can be found here. Again, this is an exclusive offer for people who have Delta Dental Plans.

SONICARE Healthy White, clearance price of $54.99
Use: $5/25
Use: 10% off Wellness Shopping Pass (-$5.50)
Use: Sonicare $10 MQ
Total: $34.49 ($24.99 after $10 MIR from Delta Dental)
