I'm not exactly cheap... but I'm very careful with my money. If I really want or need something, I don't mind paying for it, but I'm always careful not to waste any.
For instance, I always go for the bargains when grocery shopping and spend â‚¬20 a week on avarage, but I don't mind spending a little extra on local produce and eggs from free range chickens. I also don't buy a lot of clothes. When I go shopping, which is maybe twice a year, I usually replace the basics that need to be replaced and buy maybe one special item. Oh and in winter, I keep the central heating system at 18 or 19 degrees celsius during the day and 15 at night. It's better for my books and it saves money.
As for glasses, so far I've needed a new pair every three years or so, but I usually buy them when there's a good deal and I always go for the cheaper frames. Last time I got a free pair of prescription sunglasses. Awesome.
Then there's my hobbies. Yeah... let's not talk about what I spend on my hobbies...
