And once you trade for certain rares, you need to re-type everything again to see how much you need! You go to bed after a day and the next day, you have to re-type everything AGAIN!!
In Excel, all you need to do is change the value of the rare which had a change in value or the number of rares you need after making a trade and boom, everything is worked out in less than a second. At the end of the day, you can just save the spreadsheet and continue trading the next day.
I think you're better off just posting a tutorial on how to use Excel to do the calculations.
