You have to watch their sales right after the Spring Classic. A couple of years ago I traded one of my dad's old Abu rods in for a Shimano SLX. I think I got a $10 or $15 discount. I was also wanting a Bionic Blade rod to use for casting lighter moving baits, but they never had the length or power that I wanted.
About a month after the classic was over the store near me got in a shipment of Bionic Blades, and had them on sale for the trade-in price that they were advertising during the classic.
