Forum Formulas for deal comps?

Would it be possible to integrate a tab to "calculators" that breakdown deals to it's lowest denominator?

For example, often times a thread is created suggesting there's a deal for a consumable item [ie: toilet paper) , however, it's not always proven to be a true SD let alone a hot deal.

If there was a section embedded in a sub-header next to "TOP COUPONS" that was allowed for drop down calculator/formula to click and open a "comparative" tool, that would help other SDers to identify if it's something they'd wish to capitalize on.

Is this possible? or is that not of any benefit for the forum?

If this belongs in a more appropriate section, please excuse the error on my part and move accordingly.
