Two of these apps are games from Disney: Where’s my Water? and Where’s my Perry?. Each of them typically costs US$1.49, but both are now available for free.
Another great offer is The New York Times app. Until the end of January, you get free unlimited access (which would otherwise cost US$20) to news and issues at NYTimes.com.
Zinio, a service that lets you buy magazines in digital format, is also offering a US$50 voucher for mini-subscriptions and single issues.
Other apps with special offers include the EPSN app (free insider access) and Expedia (get reduced rates on select hotels).
It goes without saying that you must be running either Windows 8, Windows 8 Pro, or Windows RT in order to access the Windows Store to get these apps.
