For me, it was a pair of merrell shoes on sale. They have lasted 3+ years, have great grip in the snow and ice, and so comfortable, my feet don’t hurt after wearing all day.
Never cheap out on anything that comes between you and the ground; shoes, tires, a bed.
What have been some of your good purchases under $100?
I mean don’t worry too much, unless it physically cracks or something you really can’t ruin it.
Don’t wash it while is hot, and if you do wash with soap and water make sure to dry it very well and apply a thin coat of oil to avoid any rust build up. A metal spatula is also great to scrap the pan if it’s not too messy and then you can just keep it using.
