I know it sounds obvious but a good way to save money is to only buy what you need; you’d be surprised how many people don’t do this.
I tend to have a clear out once every 2 months, anything which I no longer need either gets thrown away, or sent to charity shops; however if you have the time you can either sell them on ebay or at car boot sales. After clearing out you can see exactly what you need, trust me it works and saves you alot of money especially when it comes to children’s clothes and toys.
Another way is for celebrations such as birthdays if people ask what you want; tell them what you need. For my daughter’s birthday people asked what I wanted them to get so said clothes in the next size, as she had nearly outgrown the current size.
