Just went to the Northbrook, IL store and they gave me the 20% off in-store on a new Tirreno Razza 3.0 to meet (well, beat if you exclude shipping) the web price. I must say I was most impressed with their quick decision to match the printout of the checkout page showing the overall discount.
FYI - it helps to bring a screen-print, so they'll just go ahead and give you the price-match.
I'd read on here that some of the stores are too cool about the web coupons, but they gave me no problems with it.
