When you come across an item that you think you'd like to buy, channel everyone's favourite declutterer, Marie Kondo and check in with yourself by asking a couple of questions: does it spark joy? Would you buy it if it were full price? It's really easy to be tempted by big discounts, and this can often lead us to buy things that we don't actually want. A bargain's only a bargain if you actually need it. Before you dive in, take a quick moment to be sure you won't regret it.
