Reasonable price for medicine ball or foam roller?

A nearby store sells both medicine balls and foam rollers (for self myofascial release).

What are good prices for both (weight of the balls goes up to 30lbs, foam rollers come in 18" and 36")?

I payed $40 for one of the ones that title sells. I used it pretty good for 5 years and was in great condition until our basment flooded last year. If I remember right it was 30lbs. It was vinyl though, I wouldn't pay that for a medicine ball coated with plastic or rubber.

Thanks. $90 definitely sounds too high then.
