Same here.
I also prefer having an exact amount of CPs and gold on me that ends with either 0 or 5 (eg. 10, 15, 20, 25, etc.)
Same goes for the amount of pots I carry, I always buy pots so I have an equal number (usually 110 or 120 mil. ginsengs)
I have a warehouse for each type of item, I also make sure I have a scroll to each city in my market warehouse too. Although I don't really need that anymore cause I just teleport to the places.
I have it in the real world too though, whenever I'm adjusting volume on the radio etc, it has to be an even number.
