Well, DH has had to eat out with clients a lot this month, so I haven't had to feed him.
That saved us a small fortune.
We've been doing a lot of our shopping at Aldi's lately, and that has saved us a lot on canned goods and frozen food. For other things, we've really been watching the ads and only buying things that were on sale. I've used a lot of coupons, plus I've stumbled upon a ton of really good sales and was able to pair up the sales with coupons and stock up on diapers and baby cereal.
I saved a lot on plants for the flower bed by checking the clearance section. They had 6 packs of plants 50% off or more because one of them was a little wilted. The other 5 looked perfect.
I also got a lot of free stuff from Freecycle and Craigslist. You just never know what you're going to find there.
I don't go anywhere unless I absolutely have to, so I'm not using a lot of gas.
When we have gone out to eat (which has ony been a couple of times), we went on "BOGO night" and "Kids Eat Free night".
