“What are going to do with that blu-ray disk of the Avengers:Endgame....?”

Sell it. Media from the Marvel movies will always be worth cash to a collector. (I sell rare/older media/collectibles on Amazon making $2000 a month by flipping your old tapes and DVDs). Physical copies of ANYTHING become rare over time, and time = $$$$$. I just sold a rare old Star Wars poster for over $100, yet you can look at pictures of Star Wars online for free.

Edited to add: Do you guys know how much a copy of this sells for now? Any price you want it to. (Also, it’s terrible, in case you haven’t seen it)
