3. Jewelry So you're going to be the genius who proposes on Valentine's Day, huh? Join the club. Jewelers of America reports that February makes up 8% of jewelers' annual sales -- lagging only behind the November and December holiday season's 32.3% and May's Mother's Day and bridal-driven 8.3%. That's a big crowd waiting to pop the question, and they could spend a whole lot less on their dinner, flowers and other romantic touches if they just waited a few days. In fact, it's going to cost exponentially more to get down on one knee and present that engagement ring this year than it has on recent Valentine's days. The Jewelry Industry Research Institute's Ken Gassman says that average engagement ring prices hit $3,500 last year. That's higher than the $3,450 average in pre-recession 2008 and far more costly than the $3,200 average in 2009 and the $3,150 suitors spent in 2010.
