I used to be that girl who couldn’t resist the “add to cart” button. A cute pair of shoes on sale? Bought. A random kitchen gadget I’d probably never use? Bought. By the end of the month, I’d be staring at my credit card bill thinking, “Where did all my money go?”
But then I discovered something that completely changed my spending habits—the “3-Day Wait Rule.” It’s so simple, yet it’s saved me hundreds of dollars each month while still letting me enjoy the things I love.
The concept is easy: whenever I see something I want to buy (unless it’s a genuine necessity), I don’t purchase it right away. Instead, I give myself 3 full days to think about it.
During those 3 days, I ask myself:
Do I really need this?
Will I still want it after the excitement wears off?
Is there something better I can use this money for?
Most of the time, the answer is no, and I forget about the item completely.
Impulse buying is all about emotions—the rush of excitement, the feeling of “I deserve this,” or that fear of missing out when something is on sale. Waiting 3 days gives your brain the chance to step back and think logically instead of emotionally.
This tiny pause:
Helps you figure out if you really love the item.
Gives you time to check for better deals or discounts.
Reduces the post-purchase guilt that comes from buying on impulse.
At first, I was scared this rule would make me feel like I was missing out. But honestly? It felt freeing.
Instead of that heavy feeling after spending money on random things, I started feeling proud of myself for choosing wisely. And when I did decide to buy something after 3 days, it felt like a reward, not a mistake.
Last month, I saw this gorgeous $80 bag online. The old me would have bought it instantly. Instead, I waited. On day 3, I realized I already had 2 similar bags I barely used. That $80? It stayed in my savings account, and I didn’t regret it for a second.
Make it a game. Challenge yourself to wait before every “want” purchase.
Write it down. Keep a wishlist instead of buying immediately.
Reward yourself. If you still want it after 3 days, buy it guilt-free because now it’s a mindful purchase.
I have a small monthly “fun fund” for guilt-free spending. If I still want something after 3 days and it fits my budget, I go for it. No stress. No guilt.
The 3-Day Wait Rule completely changed my relationship with money, but to be honest, it’s not the only thing that keeps my spending in check. Over time, I’ve layered a few smart habits on top of this rule—tiny shifts that have not only stopped my impulse buying but have also made me feel more in control, less stressed, and surprisingly happier with what I already own.
Here are the 5 powerful tricks I now use alongside the 3-Day Wait Rule to save hundreds every month without feeling deprived.
Instead of waiting until the end of the month to see what’s left over, I move money into my savings account the moment I get paid. Even if it’s just $50, this simple move means:
I’m less tempted to spend it.
I know my savings are growing quietly in the background.
I can still enjoy my purchases guilt-free because I’ve already taken care of my future self.
It feels like paying me first, instead of everything else.
This is one of my favorites! If I see something online that I want, I add it to my cart… and leave it there for 3 days.
I often forget about it, which means I never needed it in the first place.
Sometimes, I even get discount codes emailed to me because I “abandoned” my cart.
This habit makes me feel like I’m saving and being smart with my choices.
Whenever I want to buy something, I ask myself two quick questions:
Will this make me happy for more than 10 days?
Would I still buy this if it cost 10 times more?
If the answer is no, I skip it. This quick mental check has saved me from buying dozens of things I didn’t really need—things that would just end up cluttering my home.
Instead of cutting out treats, I swap them for cheaper alternatives:
I make my favorite café latte at home, with whipped cream and a fancy sprinkle of cinnamon, for $1 instead of $6.
Instead of an expensive spa day, I have a candle-lit bath with essential oils.
This trick doesn’t make me feel deprived. I still get to enjoy my favorite luxuries, just for a fraction of the cost.
Here’s a game-changer: I started taking out a set amount of cash every week for non-essential spending—like takeout, coffee runs, or a little shopping. When the cash is gone, I’m done.
It’s amazing how much more mindful I am when I physically see money leaving my hand.
I also love how this challenge makes my fun purchases feel extra special.
The truth is, I’ve realized that impulse buying was never really about the item—it was about the feeling. I used to shop to reward myself, to fill stress or boredom. But now, I’ve found other ways to give myself that “happy feeling” without spending money.
A walk in the park with coffee in my travel mug.
Watching my favorite shows with homemade snacks.
Calling a friend instead of browsing online stores.
These tiny shifts are just as satisfying, but they don’t cost me a cent.
With the 3-Day Wait Rule and these 5 additional tricks, I’ve noticed I save $300–$500 every month without feeling like I’m cutting out everything I love. In fact, I enjoy my purchases more because I know they’re intentional.
If impulse buying makes you feel out of control or guilty, try this rule for just one week. You’ll be amazed at how empowering it feels to choose what you spend on, instead of letting your emotions decide for you.
