I bought this same thing, maybe not brand, but same thing, at Costco, 2 days ago for $19.99
Hah! I was about to say the exact same thing!
(Literally 2 day’s ago as well)
My wife liked it so much, she sent me back to Costco to buy another one for the other side of the cabinet.
In-store only? I’m not seeing anything like this online.
The below is the one at costco. it is slightly thinner but for 1/3 the price, definitely worth it. I picked up the last 2 at my costco for $15 each 
I’m not seeing it on their website so probably in store only now.

When I went to look it up when I posted it, the first site I saw said it was in store YMMV.
I bought a few of these recently. While they all look similar, I discovered that some are designed and built for the loads they will carry (and balance when extended), and operate for years without binding or breaking. And some seem to not be built all that well. Be careful! The loads they carry can get heavy, especially the wider ones.
