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 bought a ~1pt sippy cup that you can’t spill, like the kind designed for children. It’s made such a difference for drinking alcohol and for parties, where I tend to slosh or spill my drink!
Plus now my cats can’t dip their paws in when I pour water and ruin the drink
