Was at the Brandon Costco today, when a couple of decent 2A deals caught my eye. Right at the entrance, that had these new metal "ammo cans" (a .50 cal and a .30 cal set) for $19.95. You can see a review of them in
this YT video. The only caveat is that there's no loop hole in which to place a padlock. You might be able to work a "trigger cable lock" on them. But they are excellent quality.
The other was for a small 14 capacity gun safe on sale for $299 (was $365). But it's probably to small for most here.
Enjoy!
