Check with your local, independent shops as well. Mine will order parts directly from Honda, and they do not charge me shipping fees. I purchased new tires online, had them shipped, then ended up having my local independent shop install them due to problems I encountered ($28 to put the tire on the rim, and balance it -- after the struggle I had with the front tire, it was money well spent; didn't even try the rear tire, just paid the man -- I hate tubes)... I asked about tires, and what they would have charged me for the same exact tires: same price, minus shipping fees (around $25 for both tires, two years ago). It pays to ask. Cheers!
