(MoneyWatch) Any excuse for a sale. The nation's retailers, anxious to boost revenue now that consumers seem a bit more amenable to spending, have launched a host of St. Patrick's Day deals, according to deal site FreeShipping.org. After all, if a day best known for green beer isn't a good excuse for a sale, it's hard to imagine what is.
