I used to wax lyrical about YC from QVC but like many of you have found they now lack strength of smell, they tunnel even with a few hours burn and they burn with a dirty flame that blackens the jar rim and even the wall. The exception being the YC I buy in Florida which don't do any of the above and produce an aroma that gently wafts around the house.
Is it possible that YC are made especially for QVC to a different "recipe", ie cheaper poorer quality ?
could well be
