So with FandangoNow officially(?) owning Vudu now and no mention of Disc + Digital or InstaWatch (that I saw) on Vudu or Walmart.Com I was doing some disc shopping WM.com

I purchased:
The Daniel Craig Collection (4K Ultra HD + Digital Copy) - James Bond
Hellboy (4K Ultra HD + Blu-ray + Digital Copy) - 2004 version

There was no mention of InstaWatch or digital copy at any point during adding to cart or at checkout.

Almost immediately I got an email saying digital copies had been added to my account! I went to Vudu and they were all there. And under my purchase history the details state "Promotion". Sadly they were HDX, not 4K. But then I was checking back a few days later, before the movies even arrived, and they had both been upgraded to 4K. Odd since in all the hundreds of InstaWatch and D+D purchases I've made I've never seen that.

Buyer beware. Your experience may vary. If you get the digital movie added you wont know till after person. Besides InstaWatch was always hit or miss. Says IW and it wasn't. Didn't say and it was. Bought 4K and you got either 4K or HDX.

Just sharing. Again buyer beware.
