Can I ask how old you are, Shy?

Pennies are very important when saving money. The dull stuff, like clipping coupons, finding sales at grocery stores, doing without. It all matters.
That means (also) no trips, no matter how good of a bargain they may seem to be....it's still money spent.

I suggest house keeping. I don't remember how much you can make without claiming on taxes, perhaps someone could help out here. I had some good clients when I had that as my second job and I was newly married and broke.

If not that, I suggest a job where you don't have to wear nice clothes (jeans or a uniform are better)...it's just less expensive that way.

That said, and if you have the clothes already, retail is a good bet this time of year, but you have to be willing to do the day after thanksgiving and Christmas.
