Today on ULTA, you can get Buy One, Get One FREE Clarisonic Brush Heads (all types are available).
Most heads are $27 each, so after the discount, you’ll pay $13.50.
However, the best deal is if you purchase four heads (you’ll have to mix and match a bit), because you get FREE shipping.
(I just bought four heads – two sensitive and two regular and it was $54 total with FREE shipping.)
If you just want two heads, you’ll pay shipping charges ($5.95)
This deal will sell out, so act accordingly.
