Great job!
Some other random ideas:
(1) When things are on sale (for example baby carrots) buy a few of the product, wrap it up, and freeze it in your freezer. Yes, some products wouldn't work very well, but it could save a bit.
(2) If you drive a car, try not using the car one day a week. This could save quite a bit! You could choose this day to walk around your town and do errands (if you live in the city), and get a workout at the same time!
(3) If you have a window or wall AC unit, use your ceiling fan at the same time. It may sound like it would cost more because your using two things at once, but it will actually make the AC unit work less hard.
(4) Slowly get rid of non-energy efficient appliances as you can afford them. In particular, getting a new fridge can usually save the most money.
(5) Instead of using gift wrap for gifts, use old grocery store bags, and wrap gifts with the brown side facing outwords. Use markers, glitter, crayons, whatever to decorate. I do this all the time. People usually like the creativity.
(6) If you have pets, then when you see that their food (and litter if you have cats) is on sale, buy a few of them so you can save a buck or two. It would cost less in the long run.
(7) Use both sides of paper that you use from your printer. Print on both sides, or cut in 4's and use as scrap paper.
(8) Clean your house. Sell old stuff. I'm currently doing this (my living room looks like a tornado hit it!) right now and I think I'm going to get a decent amount of money. One thing I suggest in particular is if you went to college and still have old textbooks that you don't use anymore, try to sell them online! I have a few books that are from 2001-2003, and they are still worth $20-$80/each!
Good luck.
