What store do you get medicine balls for fair price? Sure isn't dicks sporting goods.

This person told me they got a medicine ball for 25 bucks that was 12 pounds. Yet, when I visit dicks sporting goods online it has medicine balls at 12 pounds listed at 40 bucks and more! What a ****ing rip off they are! So, does anyone know of the store that sells them for fair prices? Also, do you recommend a medicine ball for me to try to put more muscle on? Like what type of exercises would it help me out on. Thanks!
