Retailers will have to begin showing these accumulated pools as backlog...so to speak. They are having an incredible impact, make no mistake as an alternative to giving another lgift someone does not want...these cards are a godsend.
One other thing...Holiday shopping patterns have changed, people are stalking Retailers just like good traders stalk low stock prices. Everyone knows that the 5 days after Xmas has the Best Value...give a gift card...cash it in at inventory liquidation time...no brainer...
