> Currently, only three outlets are live (Zug, Kreuzlingen, and Rossrüti). I noticed that not all the Spar outlets are tagged on OSM. I am currently filtering out the ones that are missing.

Your are mixing two things here in the same changeset which doesn't help.
If you import data (from Spar) you *have* to discuss this with the (local) community. How did you get access to the data of the Spars? Does Spar agree that you put this data into OpenStreetMap and thus gives OpenStreetMap a license to distribute that? 

> Can I share this list with you when I am done?

I don't see any sense with sharing the list with *me*, you need to share it with the community, *and* put your import plan up for discussion!
See https://wiki.openstreetmap.org/wiki/Import for details and go to http://c.osm.org/c/107 to start such a discussion.
Otherwise *all* your recent additions/changes of all the Spars in Switzerland have a big chance of getting reverted!
