firestone seems to offer b3g1 in the fall. It's hard to beat their price on this sale when it hits, around here. Big 10, sears, wal-mart is the competition. I have noticed that wal-mart carries low-end michelins (which scare me after "marrying into" a set), a few other makes, and a line of firestone tires that firestone themselves do not sell at their shops. I'll avoid wal-mart. Big 10 always charges more than firestone, and after doing tire business with both, having both bad and good experiences with both, I go with the guy that always quotes lower (big 10 would price match every time).
