Welcome from Central VA!
I'm all about saving $$ - I guess we all are on here :P Anyways, I've never checked out the Tightwad Gazette, but one of the best things DH & I EVER did was to sit down and make a realistic budget, and do our very best to stick to it. He does HVAC work, and generall makes decent OT, but there are sometimes when it gets tight. And try as hard as you can to establish a good savings, even if it's just a few $$ a week that you can add to it.
I try to garden and can or freeze as much as I can to cut down on groceries, and also try to only grocery shop once a month. Sometimes you have to get something in between (milk, etc), but we have 2 small chest freezers, and I buy my meat in the bulk pkgs and freeze in Ziploc bags the smaller sizes. I also freeze sandwich meat, cheese, butter, etc. that I buy but won't use right away.
You'll find all kinds of $ saving tips here!! Enjoy :)
