How can I create discount-based collections?

I been looking into this as well and I think your going to have to do it on the excel file. Maybe search only the items with a compare at price, export it, enter some kind of formula to show what the percentages are, and then add a tag? This way you can make collections based off the tag, ie 20%, 25%, etc… If I come up with anything Ill leave an update.
