More than likely, Sam's Club. They utilized blister packaging intended for peg hooks. What's the UPC on the back look like? Any kind or item number or ART?
Thanks, I collect passively and see I need about 30 yet. Mostly less common like '09 VDB, '09 S, and '09 S-VDB, but also a few silly commons like '14, '26, and '36 plains for some reason.
I recently purchased a king sized firm lineal mattress from Loom and Leaf https://www.loomandleaf.com/lineal and I haven't slept this well in years. It's great for people like me with lower back pain and it even has built in massage features as well as under bed LEDs and remotes.
