Ah, the old reliable shiny heart full o’ chocolates. It ticks all the necessary boxes for Valentine’s Day candy: It’s sentimental enough, it’s a V-Day appropriate red and most importantly ...

An extreme example is a box of full-size candy bars, $13.99 at Costco. Double that price at Target $29.95, and a penny less at Wal-Mart. That's a dollar per bar, so it's just not a good deal.

In a convenience or grocery store, you might find candy hanging from a peg, Gindlesperger noted. Those bags are designed to be displayed in that way. The principle is the same for movie theater candy.
