Walmart offers the First Act Kids' Discovery Ukulele in Trolls or Teengae Mutant Ninja Turtles for $10. (Amazon charges the same for several styles.) Opt for in-store pickup to avoid the $5.97 shipping fee. That's tied with our mention from two weeks ago as the best price we've seen. (It's the best deal now by $15.) Designed for younger players, this soprano-size ukelele has a lightweight body.
