i agree, some extra information about your household's income and outflow would help folks to, well, help
with that said, the easiest and way i know to save when you feel you can't save anything is to pay cash and save the change you get. it's just about painless, and can easily add up to 10-20 per month. if you're feeling ambitious, try saving your dollar bills, too. i save ones and change from my personal allowance and find i stash 20-30% without really feeling it.
another other option: when you're writing a check (say $42.23 for groceries) round up to the next dollar and enter than into your register ($43). at the end of the month, take your 'change' from checking and put it into savings.
poundwise's suggestion at looking at a part-time job is a good one, especially if you can get it at a store where you already shop (they might offer an employee discount). or, as a SAHM, you could consider babysitting or running errands for friends/family/folks in the neighborhood.
