I think everyone knows it's important to save, but how many of us have actual strategies that they use to make sure they save?

For instance, I know of a group of friends who meet up and organize a fashion swap. Everyone brings clothes and jewellery they wish to exchange and then they barter and negotiate for what they like. This way, they save on buying new clothes every other time. Does anyone have unique saving ideas or just share what works for them?

Thanks! Very helpful tips
