Depstech via Amazon offers its Depstech 16.5-Foot Wireless Endoscope for $42.99. Coupon code "QT5FCA6W" cuts that to $27.49. (It doesn't stack with the clippable coupon on the product page.) With free shipping, that's tied with last month's mention, $16 off list, and the lowest price we could find. It's compatible with Android and iOS and features three adjustable resolutions (up to 720p) and a 2-megapixel camera. Deal ends January 25.
