Many people have the quality of being an impulse buyer. I myself can be considered as one of them. I have never given much attention to that until I said it aloud. With various items to choose from, it simply is overwhelming. Without thinking about it first, the person's sense or urge of buying something that is wanted but may not be exactly needed, when evaluated, is somehow therapeutic temporarily.
For men, it is fast and easy. Just look among the options and pick, they are done. For women, it is the opposite; shopping is real. When they can buy lots of stuffs especially on sale, they will. I agree that you can never know what you will find in a sale and it can be worth the time. Many items that seem to be rare might be there that is why you have to search well.
Take my habit, for example. I am into reading and my book collection is still growing. Seeing a sale is tempting. With the thought of "I will just browse, I will just browse," I still end up leaving the store with item/s more often than not. Though I am trying to practice better self control, it is quite a challenge. Then after talking about it, I realized that I have some way around it. It is working for me unconsciously and now that I am conscious about it, I might indulge myself with it more, if necessary, to see if it works consistently.
When I thought of having another book, I search about its price and story over the internet. I will keep on reading different store websites, and probably reviews. When I close them all, I become decided to postpone buying. Thinking I don't need it right away and can save money for something else, I become satisfied. Apparently, I was able to address my impulse with those information that I end up not wanting the real thing on my hands just yet. It can wait.
The same happens when I feel like having a new gadget, like phone or tablet. I will keep on browsing and reading. When I notice that I have spent too much time on the internet, I stop, and so is my urge to buy a new gadget. I will be satisfied again with what I have, thinking that it is still in very good condition, which makes it reliable, which makes me contented.
The given scenarios are when I am at home. Being present on a store is a different thing and I am still experimenting various ways of how to get over it. As you know, anything can happen when you are physically on site. If you are an impulse buyer as well, feel free to try this method I use and do at home. Maybe it can help, maybe not. It is up to you. I will post any development I might have in the near future.
