Amazon offers its Amazon Prime members the Fred and Friends Store-M's
with free shipping
. (Non-members can spend over $25 to qualify for free shipping; otherwise, shipping costs $5.58.) That's the lowest total price we could find by $8. This pack includes three nesting storage containers.
Of note, this qualifies for Amazon's 4-for-3 promotion.
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 that currently there's a waitlist for Amazon Mom.)
