Was at my local Home Depot and spotted these in the clearance end-cap near the tools.
$1.90 each! Very YMMV as it is a clearance item. I think the regular price was $8.98.
Use Bricksee to see if your local HD has inventory. My store still had 6+ after I bought some. https://brickseek.com/home-depot-…=203263250
I’ve also attached a copy of my receipt.
