David had some rewards certificates from Best Buy available, and they happen to have the BluRay version of the movie “Rudy” in stock for only $7.99. In theory. The disc was actually marked $19.99, but rang up at $7.99, because nothing in life or at Best Buy is ever simple or straightforward. Great, so they straightened that out: now, could they pull up his certificates from within the store? Of course not.
