Not the easiest thing to complete but certainly not the hardest.
Bed bath and Beyond have a price match policy to match local and online competitors prices, Kohls has this item for $209-$10 (Promo code Home10) and 20% off with promo code HURRY. This brings the items price down to $159.20. Additional $30 off Manufacturer coupon is available online bringing the price down to $129.20 plus tax ($141.19 here in Florida). Bed Bath and Beyond is currently offering a rebate of $60 as well bringing the total cost of the item to right aound $80.
Note YMMV depending on the manager, the manager at the store i did this with was not happy but could not quote anywhere these were not allowed, and their official policy for coupons and price matching seems to be fine with it.
Best of luck! I'm loving this new toothbrush!
Here is the link to the coupon for $30 off
Coupon should also be available here but I used the above link
