It isn’t easy to find stock-up deals on pricey power toothbrushes, but this week CVS has provided us with a couple of opportunities. Earlier, we told you about a deal on Oral-B power toothbrushes. Here’s another great deal on Colgate battery-powered brushes. Pay the sale price of $6.99, use a high-value $2.00 coupon from the 9/20 Smart Source insert, and get back $4.00 in extrabucks. Even better? This deal can be done twice!
