YMMV Nest Protect (3-pack) – $110 Sam’s in store

Found the Nest Protect Gen2 3-pack (battery version) for $109.71 in store @ Sam’s (West Texas)
It is still $329 @ Sam’s online ( link for reference )
Shelf tag said $145 & there was no display or spot for them on the shelf – I found the only card behind some thermostat cards, so it had likely been there a while. Then it rang up $109.71.
They checked for more & said it was discontinued in store after looking it up.
Very YMMV I assume.
