Sell, Sell, Sell
Simplicity is key to an inexpensive household. Go thru your clothes, jewelry, dishes etc and purge.
Set aside a reasonable amt for you to keep on hand. For me a tote of clothes on top of the 10 outfits we currently have set out is reasonable per person. Extra clothes means two things. Some never get worn or we spend 2X the amt of time doing laundry. That also costs $. Set aside one set of dishes for you to use and some for when you have company. Go thru your jewelry, CD's, DVD's etc and see what you can sell there. Not only can you make some extra $ but you can make things simpler. Simple lives are less stressful and less expensive.
Places to sell include consignments, online stores, Craigslist, Ebay, Amazon.
