Amazon offers Amazon Prime members the Logitech Harmony 300 Universal Remote, model no. 915-000143, for $19.99 with free shipping. (Non-members can spend $25 or more for free shipping; otherwise, shipping adds $5.58.) That's the lowest total price we've seen for a new, factory-sealed unit by $2 and a current price low by $8. This remote supports up to four components and features online setup via Mac or PC.

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.)
