Impulse buying is something every retail store has to keep in mind. I run an adult toy store. When we get something in that has possibly joke nature, we have to decide how we're going to price it. Sometimes a difference of $2 can make the difference on how a person percieves the item. Sometimes we can sell a LOT more of an item dropping it just that $2

I have mostly been able to buy my Videogames in a planned list.

First I take note of what games are coming out, I then take a look at my budget, I then estimate how likely it is going to be coming out either in a certain year or on a certain month.

Sometimes it is annoying how a game you wanted is delayed or unexpectedly canned. Or is been given an AO18+ rating as it has happened in a few rare occasions (more likely happens in Australia because of the lack of an R18+ rating for videogames)

There is also an issue of a number of games from Japan that when you hear about them, you wanted to buy them but they never get released outside of Japan or even into Europe. (As an Australian I rely on games being released in Europe first.)

The only occasion when I impulse buy is when I see a game I was half hearted about (as in I would like to get it if it was not being sold at a high price) being sold for 30$ or 20$ in Australian Dollars.

Other than that, I rarely buy on impulse except for special occasions when I have the money to spare. And if I don't like the game and I don't want it anymore then I trade it in.

A few days, I bought a used copy of Jusitc league Heroes for PS2 largely on impulse. And I'm Canadian.

I also bought the Transformers: Revenge of the Fallen DLC from the Playstation Store largely on impulse.
