The busiest part of baseball's shopping season is now in full swing in Nashville, Tenn. If you've ever subjected yourself to the indignities of navigating a crowded mall or big-box store this time of year, you've probably experienced that dreaded disease that holiday shoppers are prone to contracting, buyer's remorse.
