I went to my local dealer to get a set of blades and the nut and bolt for one of the anti-scalp wheels for my ZT yesterday. Dealer didn't have them in stock. Said he would have to order them. He then charged me $7.50 for shipping. Do you charge for shipping on common parts like that? I can understand if it is something odd. I would think that the dealer would want to keep a set of blades in stock at all times. By the way, he charged me $15.95 per blade. Is that about right? Thanks.
