Whoa mama! $85
!
I believe at our local Woof Gang Bakery, they charge $35 for wash/dry/face/paws/nail trim/sanitary area and $45 for all of that plus doing the body hair. I love our groomer and have always felt comfortable leaving Toki in her care! My sister gets her yorkie groomed at Petsmart and they really bend you over there. I want to say that she spends around $55 (before tip) or even more for a full-service groom. I don't mind paying for great service but I feel they charge too much for essentially a puppy cut and nail trim, especially considering the level of experience a lot of the groomers there have (I'm sure there are good groomers there but I'm just speaking from my experiences).
But $18 seems like a pretty good deal for all of the stuff you're getting (if your groomer does a fantastic job, it's a steal!)
