I would like to add that this would be especially helpful for eVars set
to Original Value. For those eVars, you almost always have to expire
them after a timeframe, or risk winding up with zombie values in the
reports.Let's say you have an eVar for "original search keyword" on an
ecommerce site, and want to see which search terms people use to
initially find (and buy) products. If you have the eVar expire at
purchase and someone doesn't make it all the way to purchase, then they
could come back ...
