I use those Chaparral ads to get Dennis Kirk to send me the same tires for $1 less.
First set of tires I needed to buy for the B12, Chappy was out of stock, so I went to DK - and have been happy with their service ever since. Their prices are always high,, so you have to make them live up to the price beater guarantee, but it's never a hassle to do that if you have the page # and issue of the Chappy ad.
