A "free gift"

Found in the mailbox today in a tidy little plastic case is what purports to be a free copy of H&R Block TaxCut software. Is this a widespread mailing? Why to this household? For the past several years, I've been happy downloading IRS electronic forms and then double-checking my work with the free TaxAct software. Sometimes there are last-minute changes in the tax forms. Will this TaxCut update the way that TaxAct does?
