New Harbor via Amazon offers the Universal 3.5mm Retro Phone Handset
in Red, model no. 88015118, for $2.49
for shipping. That beats our mention from two weeks ago by a buck and is the lowest total price we could find for this handset. (Several Amazon third-party merchants charge pennies more.) It's compatible with most cell phones and features a 3.5mm jack, noise-reducing technology, and more. Deal ends August 7 at 10 pm ET.
Of note, eShopic via eBay offers it in Black for $7.95 with free shipping.
