Percentage Corrections & Estimating Potential Profits (updated)

I am writing this post on James' behalf.
He made some updates based on user feedback and fixed a few minor things on his spreadsheet. 
You can download the revised version here.

Changes:

+ Prevented macro from hiding "CardsMTGO3" tab; folks use this as reference to enter prices into other tabs.

+ Made table on "corrections" tab (hidden) now go from +100% to -100%

+ Updated drop down menus to pull from new "correction" tab ranges


Thanks James!
