There is one benefit to the promo I overlooked earlier, however. The resulting codes issues to the referrer are good through early Feb 2010, after the DELTATRYGOGO expires. While there is likely to be another promo to replace it at the turn of the year, some may want to stockpile a few freebies for Jan/Feb.
