Yeah I got Infinity War day one, (probably will get Endgame as well) but Black Panther & Thor Ragnarok I was able to snag for $7 brand new on Black Friday last year.
I used to justify that getting a combo with at least 3 formats (DVD,BRD, and digital) was worth $20, but now when the price goes up, and the formats are fewer, just to push 4K, I'm definitely OK with getting them on sale, or used. I did eventually jump on the Blu Ray bandwagon, but not until the whole HDDVD/BRD format war was over, and not until I got an HD TV (which was 2011). I'll do the same with 4K. I don't anticipate needing a new TV any time soon, so I wont need a 4K player for a while yet.
It is odd, when I look back at all the MCU releases I have, they are inconsistent, but I just have the ones I want. (which is basically all of them except Dr. Strange and Captain Marvel)
IM & IH I don't *think* had Blu ray releases initially, but I think they followed soon after. I have IM2 on DVD which came with a digital copy that you could download onto your computer. CA1 was my first MCU Blu Ray. CA1, Thor, and Avengers all came in combos, and had digital copies you could download onto your computer. IM3 came with my first UV copy, but I didn't use them at the time, so it expired.
Thor 2 was the first home media release under Marvel/Disney proper (no longer under Paramount) , so they started ditching the DVD combos and just doing BRD/Digital, or BRD/3D/Digital. This is how I got Thor 2, Winter Soldier, GotG, A2, and Ant-Man...I wonder what I'm ever going to do with those 3D Blu rays
.
The rest have just been BRD/Digital when I can find them on sale or used.
There are no more good TV Shows, only ones that haven't disappointed me yet.
