Amazon offers its Prime members Battle Royale: Complete Collection on Blu-ray Disc for $15 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping adds $2.98.) That's $2 under our mention from two days ago and the lowest total price we've seen for this collection. (It's also a current price low by $11.) It features three Blu-ray discs plus a bonus DVD with more than two hours of special features.

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months.
