I just realized that a few products were showing to be discounted.
Reviewing specials, those products were special but expired in 2014. Status box is RED.
Deleted the special and discounted price is still showing in red with original price struckout.

Other than that, I have done no troubleshooting.
zc1.5.4 upgraded from 1.5.3 in July 2015 by uploading the zc1.5.4 changed files after verifying no core edits to those files.

This is one where the special has been deleted

Ideas? Things to check?
