Walmart offers the Hohner Blue Ice Harmonica 3-Pack for $9.48. (Amazon, Musician's Friend, and Butler Music via eBay have it for the same with free shipping while Guitar Center has it via pickup.) Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our April mention and the lowest price we could find by $3. It includes a carrying case and plays in the keys of C, D, and G.
