Brad's Deals Editor Michael,
This Pursonic S520 Ultra Sonic Electric Toothbrush Set with 12 Brush Heads that would normally cost $89 is being offered for $39 at MorningSave. Shipping will add $5. Only Amazon Prime members can purchase this set for the same price after shipping, but for everyone else, this is the lowest price we could find by $10. Along with the rechargeable electric toothbrush, this set comes with 12 brush heads, two hygienic travel caps, two interdental brush heads, two tongue cleaners, and two floss holders. A one-year warranty is included, and there is no sales tax (except CA and TX).
