Things to Consider Before You Buy

1) Does this item have a purpose?

How often do you buy something because it’s a good deal and you might use it later?

Just because you might use something later doesn’t mean you should buy it. Instead, challenge yourself to ensure everything you buy has a specific purpose.

I can’t tell you how many times I’ve bought “just a few more” organizing bins at Target because I *might* want them later. While I often did use the bins later, I also spent quite a lot of money that wasn’t in our budget, creating more stress and hassle for my whole family. The simple truth is that it wasn’t worth it for a pretty container.

2) How long will this item last?

Have you ever thought about those little toys and do-dads from the Target dollar bins or the dollar store? Those items are often so cheap that they break the next day. Even if something was just a dollar, it’s still a dollar less you now have. While that might not seem like much, it does add up over time if it’s something you regularly do. Think about the long-term use of something before you buy it.

3) How much will we use this?

This question is true for many items we buy, but toys and clothes are the top things I think about with this question.
