We really watch the little things we add to the shopping. DH is the worst for seeing personal stuff he thinks he needs and throwing it into the trolley like deoderant. He has about 6 deoderants going at the moment. Even foods like pasta, bin bags, tissues and tinned stuff he's alway putting in and we have about 4 packets of pasta, 6 boxes of tissues...I'm sure you get the picture! I have told him to stick to the list now!
We were also using the dryer alot through winter even though we didn't really need to we just got really lazy. So now we make sure we only use it if it's raining or if things aren't dry.
We looked at our internet and phone contracts to see if we could get better deals. And our electricity and gas too.
