Disney Movie Club...current VIP offer is 60% off (there is also a 50% off offer). I have everything but Last Jedi-already got it-and Rise of Skywalker-not eligible-in my cart plus anything I needed (Pixar's and Disney's...16 total 4K discs) for $244.
The price is going to change by release day, but $150 for 9 UHD's? That's about $17 each. I'd be completely and utterly shocked if the price of the box was that low at release.
