D and I have come up with a couple of new frugal initiatives this year -- relating to food stuffs. He was decided to drink less expensive coffee. That is a big one for him as he has been a bit of a stickler. He will be saving the "expensive" stuff ($17 a pound) for special occasions.
For me, it is less expensive chocolate. I would spend $8 for 1/2 pound and I have found just eating dark chocolate bars or chips to be good enough that I don't miss the other.
The other category that we are considering is vitamins. We take a number of different kinds and I'm going to seriously look at cheaper over the counter substitutes and see if it is worth making the change or make the change and see if I notice a difference. This costs $500/yr right now for supplements that are ordered through a health professional.
