I still had that money in the GE so I decided to flip with it. It appears that unlike a year ago**** buying limits are more strict and you can't keep buying more items past the limit even if you've sold them. This puts an obvious damper on my Maple Log strategy.
I'm just messing around with different (f2p) items right now. I would like to continue doing some flipping though, so it depends if I can find decent items. I probably won't update it to the extreme like I did because taking note of exact numbers is a pain.
