I've looked into waxing at quite a few places, and even with a $5 tip Zara's is by far the cheapest. Only $25 for a full brazilian bikini wax, plus that extra $5 because the little Russian woman who does it is not only cute and funny, but very efficient and thorough. I highly recommend it to anyone with waxing needs in phoenix.
Pros: cheap, fast, great service, friendly
