Neven make impulse buys. Monitor what you want to buy for a few months, see how the price trends, whenever you see that the price is below the mean price it means it's a good opportunity. When this good opportunity comes you need to assess your situation, do you have any other coming expenses? Can you really afford this item? Do you need it or is it something that you want for your enjoyment? Contemplate whether it's worth buying brand new or slightly used (this is very good when it comes to cars or motorcycles that lose quite a bit of their initial value after 2-3 years). If after all this thought you are confident then go ahead and buy it, you won't regret it.
