Trying to find an old post regarding impulse buying calculator?

As the title suggests....

There was an old post in this section and i think it came from Coffee Journo Man(?).
It was a calculation to help decide if the impulse buy item is really worth impulse buying.

If anyone knows where i can find this post, i would be very appreciative

Thanks!
