Amazon offers its Amazon Prime members the BeautyBlender Sponge 2-Pack
with free shipping
. (Non-members can get free shipping with orders of $25 or more; otherwise shipping adds $4.98.) That's the lowest total price we could find for this quantity by $6. These makeup applicators are washable, re-useable, recyclable, latex free, and anti-microbial.
Amazon Prime membership is $79 per year; however, Prime is free for college students for one year, and free for parents and caregivers for three months. (Note that currently there's a waitlist for Amazon Mom.)
