Hi K..
My husband works, but being a military wife, and moving around alot tends to make the bills higher than normal.
Have you tried selling on Ebay? It's not that hard to figure out, and if you are a SAHM, and you have the time, it can be very profitable.
I decided a few years ago to start selling on ebay to make up for my shopoholic tendencies, and now I have my own store.
You can start small, look around your house for things you don't want, or don't use anymore, such as dvds, collectibles, books, clothing. Remember to take good photos. Once you have made a small profit, you can even move up and shop places like your local thrift stores (they always have clothes new with tags hidden in the racks), discount stores like Suzies, or DD's Discounts, or even the 99 cent store or Dollar Trees, for collectibles, cd's, dvd's, and even clothes.
Hope that gives you another Idea. :)
