I guess Discover wants in on big year end purchases. The promotion:
Buy BIG. Save BIG.
Receive a $30 statement credit when you spend $1,000 or more on a single-item purchase between November 1 and December 31, 2013.*
You can take advantage of this offer, up to three times—for a total of $90 in statement credits.
