Amazon offers Prime members The Karate Kid Movie Collection on DVD for $3.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's tied with our January mention (which required pickup), the lowest total price we could find by $3, and the best we've seen. It comes with Karate Kid I to III and the latest movie with Jaden Smith.
