I got my Avid V4's for $75/tire
Did you know Sears will price match an online price?
Check out
www.discounttiredirect.com, find the ones you want, print out the page, bring it in to Sears and they'll match it plus $7.50/tire (what they estimate you pay for shipping)
P.S. I got the price for my tires off a cheaper site, but I can't seem to remember the url right now
