I've been more frugal only in the sense that I am cutting my spending in order to be able to donate more. I've been living minimally for a week (not suffering, just skipping things like newspapers and sodas), and managed to sock away an extra $20 to add to my donation fund, as well as spend more on care packages a friend is making to send to her family members who resettled in Texas...they literally need everything from toothpaste to shoes and a lot of stuff in between. I'm probably going to stay on this regime for a while in order to keep helping them out, but really, I'm pretty frugal to begin with so there isn't a lot more I can cut back on, these savings are coming out of my "mad money" fund.
We also decided that anything left over from our Disney trip budget for next week is going to be split evenly between our savings account and America's Second Harvest. We're bringing the same amount we did for our last trip, but with the free dining, I think we won't spend nearly as much, even if we do buy souvies and gifts for families. We have $600 each to bring, for a 5 day trip with 3 park days. I suspect a good chunk of that will come home with us- I brought home over $100 last time, and we didn't really deprive ourselves of anything, just ate in the room a couple of times because we felt like it.
I'm also trying to get DH and myself into better habits about our energy use, as I know that fuel prices this winter are going to make our utility bills jump dramatically. If I can get us acclimated to things like closing doors to preserve room temperature, cutting a minute or two off a shower, not having to need the light on in every room, etc, once winter comes it'll be easier to keep up those little energy-saving habits, and by then, it probably will make a difference.
