I've found that my local shops will match most internet prices. I just ordered a new PR3 front and they matched Motorcycle Superstore's price and they will still give me the in-house rate for mounting ($20 off the bike, $35 on the bike). Never hurts to ask.
Also, just checked my email, you can get an additional 10% off Michelin tires at Motorcycle Superstore with the coupon code M351-MICHELIN through 5/23
