No matter what their budget is, everyone loves a bargain. What item or object do you love the most that cost you the least?

When I was in Coober Pedy in Southwest OZ,  we went out to a site which I thought looked familiar. It turned out to be the scene
in Mad Max Beyond Thunderdom where Max steps up to a bluff and looks over at Aunty Entity's city in the distance.
I remarked to the guide it looked familiar and he said "It should. It was scene in Thunderdome"
All over the ground were beautiful black shiny pebbles, iron ore.......
I pocketed a few and brought them home along with a few pieces of iron pyrite that I picked up in Silverton,
New South Wales..........I value those and the little husks from gum trees
which they use to make the little 'Gumnut babies'.............none of it has any value, but they do for me.
