I allow myself to pay more for better products from time to time, even though the product type itself isn't considered luxury. I just get a more expensive and high quality brand of that item. For example, I'd sometimes opt for imported corned beef in a can or I'd spend for imported snacks.
When I can, I generally try to buy organic meats and dairy. I wish I could buy all organic all the time, but I can't afford it. They pump the most chemicals in conventional meats and dairy products, so buying organic versions of those are pretty important.
