Do you have a Big Lots store near you? Fantastic deals on all kinds of stuff especially bread ($1.50 for the good stuff), toilet paper ($5 12 pk of double roll), paper towels ($5 for 6 pk of half sheet rolls), laundry soap($6 for the 100 load Sun brand) and cleaning products.
I often go there first before I go to the grocery store.
Also, I bought grocery store coupons, $5 off $30 or more on Ebay. I believe I spent about $9 on 30 of these.
I switched from Sprint, $65+ per month, to Metro PCS at $50.
If you can afford satellite tv, Dish Network seems to have the best deal, at least in my area.
And thrift stores are a life saver, kind of fun too!
