Hey MB!
The problem with (E) is that it's too strong, too broad in scope, for this argument. The critique in the last sentence isn't of "making consumers feel lucky," it's of "using advertised price cuts" specifically ("Promotions
of this sort...").
(C) on the other hand speaks directly to the one approach this argument cautions against: advertised price cuts. It doesn't go so far as to completely condemn them--they might make bargain-minded consumers feel lucky, after all--but does imply that they're not a perfect solution, hence "are overused" (from C).
Be careful not to overstate the author's point.
Note too that the question of "why?" we can ask to test the answers is provided in the stimulus: advertised price cuts reduce profit margins and undermine loyalty. Which answer choice does that information support? Answer choice (C).
If you asked "why?" for (E) the information in the stimulus would make no sense:
(E) "Making consumers feel lucky is usually not a good formula for retail success."
"Why?"
(Stimulus) "Advertised price cuts cut into profits and customer loyalty"
"....But what does that have to do with making them feel lucky?"
I hope that helps!
