When I lost my job we had to cut a lot of expences to make it work... here is somethings I did:
First call around for insurance quoting... I found that I could save nearly $800 a year between the home owner policies and car insurance if I swiched companies.
Look into the utility factors...
phone, internet and dish - I found a package that fit us well, but cost us nearly $30 less a month, but we didn't loose anything we wanted.
electric & gas - look into things like PIPP and HEAP... not sure what your income is, but they do help with utility cost for lower income families & with the new PIPP Plus programs, you don't have to have a bank of unpaid amounts like the old PIPP left lower income people with... My electric & gas went down by nearly $150 - 200 a month.
Also, if you get PIPP or HEAP you qualify for a Life Line discount on your home phone (makes your land line around $8-9 a month) or to get a free basic cell phone with so many minutes.
Next is housing...
if you don't own your home, see if you can find somewhere a little cheaper to rent or even buy that still fits your needs
if you do, see if there are any programs availaible to reduce you morgage payment... there was a Federal Making Homes Available passed & in Ohio there is a grant (save the dream) also available for families that have had major change in there situation since they bought there home. Which pays part of your morage for a up to 15 months but not to go over $15,000 per family. But with this you have to pay back part of the grant if you move within 5 years... so know going in you will be there for 5 yrs or pay back 20% per year not there.
food...
depending on income - if you are expecting or have a child under 5 you may qualify for W.I.C. (Woman, Infants and Children). The offer coupons each month to help with healthy food purchases: expecting moms & kids 1-5 - eggs, milk, cereal, bread/grains, fruits/veggies, peanutbutter or beans, & juice, plus tuna and cheese for nursing moms, where as infants get formula, infant cereal and jarred baby food (fruits/veg all babies and meat for nursed only babies)
coupons always help... check your stores to see if they take printer coupons and if they have instant ones you add to your advantage card. Plus, look for double coupon days or stores - the Giant Eagle around here does double coupons everyday up to .99, plus you can stack their instant coupons and manufacturing coupons... and if you have a buy one get one (but they do not take printer B1G1 only cents off) and 2 coupond for .50 off you can use all 3 coupons on 2 items. But look into your store & their rules for coupons.
Something else I have done is use coupons on an item I have a rebate check for as well... for example formula - you get rebate checks in the mail if you sign up for them on the formula websites, then you get a coupon for $5.00 off a can of formula - if you use both the rebate check for sometime upto $12.00 and the $5.00 coupon - you actually get paid nearly $4.00 for buying the $13.00 can of formula - lol.
Try to buy as much as you can on sale & if you don't have issues with the "cheep" food by the some off brand stuff. But most of all start watching the small printed per unit price not just the actual price of the items, sometimes you can get name brand for less the then off brand & sometimes you are better off buying 2 small jars insead of a large jar of something. Sounds odd, but it is true.
Next, road side veggie stands... they usually have the freshes, best tasting and cheapest fruits and veggies you can find. So if you like fresh foods check them out. Or of course it's to late this year, but plant a few plant yourself. 3 or 4 baby tomatoe plants only cost about $2.00 at a greenhouse, but if they grow they give you tons of tomatoes and just one or two bought in the store will equal out the plant cost... same with pepper, cucumbers, squash and zuccinni. Not to mention canning can be rewarding (although it can be a lot of work).
We also cut out eating out - cooking is much cheaper!
As for entertainment...
we put a pool in our backyard - one time buy & we don't have to pay for a pool membership (although there is upkeep costs)
we love to walk in our local Metro Parks and the kids love seeing the nature... but most of all it's free
I take the kids to the school playground, since it is the closes playground & we usually walk since it is just 3 blocks away.
And lastly gas for the car...
we shop at the grocery store that offers us the best fuel perks... which around here is Giant Eagle. Plus if we need something for HomeDepot, Staples or any other store that Giant Eagle sells gift cards for - we by a gift card so we get fuel perks for whatever else we need else where.
I know this is a long reply but I hope some of it is helpful... good luck trimming your budgets corners to make it work :)
