$20-30 as well. I don't really go to high end places for a mani/pedi... so not worth the money, IMO. Why pay more when the places I go to do just as good of a job?
At a "nail salon" it'll cost around $40-$55/$60. And because our beauty industry is not regulated - you really have to be careful with where you go. I usually go to the SPA for mine and it'll cost $85.00 for a regular (trim/cut/polish) and then anywhere from $95-$115 for specialty pedicures like stone pedicure or pear/sugar scrub pedicure.
$20 for a spa pedicure + $5 for french. They do an amazing job, exfoliate, hot towels, leg massage. I've had the $75 fancy spa pedicure and it's no different.
