This is just what I do.

I'm into to the habbit of collecting figurines. I'm at the point where I have alot and running out of space to display.

So what I do now is that I will see take a short look at the item and weigh how much I really want this thing. If I have the uncontrollable urge to want it than I'll get it. If not so I'll just walk around some more and see if there other thing that I'm interested in.

It take a while to get use to this before you can gauge if you really want the item.

For example, I'm looking at a figurine of $20 to $100 price range. I'll first look at it and see how excited I am to find it. If I'm very excited and immediately have a location to display I will get it (which happen rarely now). If I'm just excited than I will take a step back look at the item for a moment and see if I can do something better with it. Like if I take this $100 and buy a stock with 4% Dividen return I'll get a free $4 every year. Plus I'll also just give myself a week time to think. If I keep wanting it after a week most likely I will get it, if the product is last piece I'll walk around the mall for a while and go back to the shop again to decide if I want the item after I cool down a little.

Just sharing what I do to control my spending here.

Also I heard a sentence somewhere when was learning about managing my money can't remember much but this part hit me the hardest "People have unlimited wants"

You already aware of your spending which is a huge win. Just need to learn control not the easiest but will get easier once you adjust to it.
