Amazon offers its Amazon Prime members Voltron Defender of the Universe Collection One (pictured), Two, Three, Four, or Five on DVD ranging from $3.95 to $11.98 each with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $2.98.) Each season is at the lowest total price we could find by at least $12 and as much as $25. Buy all five DVD sets and they combine to take up five times as much shelf space. Of note, each is sold by a third-party merchant via Amazon, but they are all still elligible for Prime shipping.

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. (Note there is currently a wait for the Amazon Mom program.)
