It is Valentine’s Day, but for flower and chocolate retailers, today is really the SuperBowl. 1-800 Flowers founder Jim McCann said the amount of business this week is 10 times of a normal week. Godiva Chocolate’s CEO Jim Goldman expects his company to sell 36M boxes of chocolate today alone.Cocoa prices were down for the most part in 2011, most noticeably in Nov. However, demand from retail customers has been holding up. This can be interpreted as a good sign of an improving economy.
