I just happened to wander into Hibbett Sports today and found that they were clearing out their 'metal' hex db's. Unfortunately, they only had 70's, 75's, and 95's.
70's @ $22.97 each
75's @ $24.97 each
95's @ $30.97 each
That's roughly .33/lb. If you have a Hibbett's, you might wanna see if they too are selling them. The manager said he thinks they're replacing them w/ the rubber covered hex db's. They were $1.25/lb.
