First let me explain why there are no more Random money items in the shop. I decided I would try an experiment to see what the results would yield. I bought all 50 Random Money items. It cost $3750 (or points). Now logically thinking, in order to at least get my money back, I needed to get at least 75 on every roll. Near impossible, considering it can go to -190 (which it did). I didn't keep track of how many were positive and how many were negative (I should have). I only kept track of my final amount. Now let me remind you that a long while ago, there was a loophole where you could put your money in the bank and it wouldn't pull it from you. That is gone now. To keep this kinda short.
$3750 spent on items
$651 earned with all 50 Random Money items
$840 was the highest it got
-$40 was the lowest
Overall: -$3099
Totally not worth it. Just like alcohol. Always in moderation.

EDIT: Also, the red balls will still not take any points from you if you have no points in your pocket. (i.e put them all in the bank before you throw a ball to avoid losing points if the person drops it).
