Tick the coupon code in the product listing. I've used one (not this brand) to redirect the HDMI cable from my laptop to my extra monitor out of the way of my mousepad. Also good to reduce strain on cables for tv etc.
Edit: whole bunch of their stuff 65% off on the coupons page. https://www.amazon.com.au/b/?ie=UTF8&node=8197393051
Edit: up/down adapter out of stock
