Maximal Power Products for 25% off via Prime

Amazon takes an extra 25% off all Maximal Power products. (Discount is taken during checkout.) Plus, most items qualify for free shipping via Amazon Prime. That's the first general discount we've seen on these products at Amazon. Products include camera and camcorder batteries, chargers, flashes, cases, and more. Offer expires February 4.

A best bet is the Maximal Power Canon Compatible NB-6L Battery (pictured), model no. DBCANNB-6L, for $4.80. During checkout, it drops to $3.60. Get free shipping via Amazon Prime. (Non-members can spend $25 or more to get free shipping; otherwise it adds $5.58.) That's $6 under our mention from three weeks ago and the lowest total price we could find by $5. It's compatible with select Canon Powershot / ELPH digital cameras and select camcorders.

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.)
