Fudge stripes! Store brand fudge stripes are terrible! They're like fake chocolate flavoured chalk!
I don't like supporting brands in general, and don't often go for these (lil cookie/biscuit thingles with chocolate on the bottom and striped across the top) but only the name brand is tolerable :-\
Counterpoint, I got addicted to cheap shitty cookies and a 24 pack of the value version fudge stripes for $1.25 started a very horrible 2 month period of eating a pack of those daily
