We've been to Snip-Its and of course the kids love it, but it's a haul for us to get there on a regular basis.  We went to Snip Its for the first [and second I think] haircuts because I was unsure how the kids would react to the haircut.  But now I know they are good and we just go to Supercuts.  It definitely varies by location, but we've found that going first thing on a weekday or Saturday, we jump right in the chair and we're done in 5 minutes.  I just remember when the "mom" stylists are on and go then.  You can sign up to receive haircut reminders at Supercuts' website and you get a coupon with every reminder email too!  I think the kids' haircuts are about $13.
