For its Prime members, Amazon offers the Reese's Peanut Butter Cups Snack Size 10.5-oz 6-Pack
for $14.90. At final checkout, it drops to $12.90
with free shipping
. (Non-members can spend over $25 to qualify for free shipping; otherwise, shipping is $8.14.) That's the lowest total price we could find by $12, although we saw it for $3 less in April.
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.
