Weme via Amazon offers its Weme 4-in-1 Mini DisplayPort to HDMI/DVI/VGA Adapter Cable in Black or White for $14.99. Coupon code "ONCZNF8O" cuts the price to $5.88. Plus, Prime members bag free shipping. That's tied with our Black Friday mention and the lowest price we've seen. (It's also $4 under the best deal we could find for a similar item elsewhere.) Compatible with Thunderbolt 2, it supports video resolutions up to 1920x1200 and 1080p and features an audio output converter and gold-plated connectors. Deal ends December 31.
