That’s the cheapest I’ve seen the box of 14 treatments sell for.
The Oral B 3D White Whitestrips are on sale again but this time they have the box of 14 treatments marked for $18.99 each which slightly cheaper than the last few times I’ve seen these go on sale and it's a whole lot better than paying $29.99 for the same size box at Priceline.
The whitestrips also come in a box of 28 treatments but those have only been reduced to $35.99 s box which is actually higher than the last few times I've bought them on sale.
A bit of FYI in case you haven’t used them yet - the whitestrips are basically thin, flexible strips that are coated with a tooth whitening gel that contains hydrogen peroxide. These are designed to conform to the shape of the teeth and they work by holding the whitening gel to the teeth.
I’ve gone through a few boxes of these whitestrips now and I have to say that although it is a little hard to keep the tips in place sometimes (because of their super thin size), you can really get some good results once you get a hang of how to use them.
