In my experience... computer mice.

I can pay 80 dollars for a gaming mouse that dies in 6 months or I can buy a 7 dollar walmart mouse that dies in a year. Realistically how your mouse settings are configured matters more than the type of mouse you have and I have had bad experiences with more expensive mice dying under the strain I put them through. i.e usually the middle mouse wheel/button dies first because I use it A LOT. And if the damn thing is going to die in 6 months to a year anyway I may as well buy them in 6 packs and not bother throwing 10+ times tge money at them.

Mascara.

Cosmetics. Maybe not women cosmetics, but the expensive moisture cremes and so on only add stuff you don't want on your skin. Btw, "natural" marigold cremes are really bad there.

I'll go with shoes and clothes (not the work kind)

That does not mean that I'm going out to buy the cheapest I can find. I just mean to say that I don't buy expensive ones.

And my definition of expensive is $100+ I always make sure to not spend more than $50 on a shoe or any item of clothing (shirts, t-shirts, shorts, jeans)

There are only a few things, I find, worth shelling out a bit for. British tea brands (British émigré), boots, and ale come to mind. Some other things you're taking your chances a bit if you don't spend a bit more, like bikes, electronics, and musical instruments. Otherwise I'm a stingey aul get and it does me fine.
