We have CFL bulbs in all lamps, etc. - saves electricity.
I cook. I brew my own coffee.
WE use BOBBLE instead of purchasing bottled water.
We recycle, re-purpose, reuse.
I use coupons if the store is on my route...so I also save fuel.
The only item I never scrimp on is bathroom tissue....I will save on other items, but I must have Charmin!
