OK ... with the help of some of you here I have modified the code to 766 bells instead of 999 ... wasnt that hard once I understood where the number was and that it was in hex.

I wanted to change it from 999 partly because that number shouts "hacker" and partly because it is just too much money to offer turnip sellers.
Part of the fun of the game for them is needing money and working to get it.
766 might even be too high if offered too often.

Thanks to those that helped me adjust the price.
