Vudu has Apollo 11 (Digital 4K UHD Documentary) on sale for $9.99. Thanks dmeloche1
Note, this film is a 'Movies Anywhere' title and will port to other linked digital content providers such as iTunes and Microsoft Video; as well as in HD format to VUDU, Amazon Video and Google Play Movies (learn more).
In commemoration of today's 50th anniversary of the Apollo 11 moon landing, Vudu has the documentary in 4K UHD on sale for $9.99. This matches a previous front page deal at FandangoNow. This film is MA compatible so it will port to the other standard linked accounts as well (though not necessarily in 4K - some may only port in HD).
