P.S.
When I wanted to start cutting down, I calculate what I spent a day (I added up all receipts and divided it by how many days in that month). At the time I did this, it was anywhere between $75-125 a day! That covered everything from grocery shopping to bday gifts to lunches/dinners out. This included anything I charged, used cash for or wrote a check for. This did not include bills like house and car payments.
So, I put myself on a daily budget - I couldn't spend more than $125 a day (I know that sounds like alot but bear with me). If I thought I had to spend more than that on a particular day, I wouldn't spend all my $125 one day and let it carry over to another day. The next week I lowered it to $100 a day, and then to $75 a day...mind you this was a long time ago but I can now get by on spending $25 or less and that includes grocery shopping and entertainment for my 5 yo this summer. If I want to go Starbucks one morning but I know I'm meeting a friend for dinner that day, I just don't go to Starbucks.
I also cut out going out to eat, even if it meant we ate sandwhiches for a week cuz I didn't feel like cooking. We spent almost $500 a month on going out to dinner and lunch alone, and at the time it was just my husband and I and were were DINKs (double income, no kids) on top of that. Now we are on one income, have 1 child who is involved in alot of activities this summer and we have more money in our checking and savings than when we were DINKs.
gl and hth!
