I am not a collector, but this is what I got this month:
In fact other than this I only have Interstellar, Gravity, and Martian extended edition that I bought in 2021. Pretty much nothing.
Info (all prices include shipping costs):
Unstoppable DVD was new, bought from "RAREWAVES" for £4.51
The Core DVD was used (formerly rental disc), bought from "musicMagpie" for £4.74
Apollo 13 DVD was used, bought from "mommox co uk" for £4.36
Back To The Future Trilogy DVD box set was used, bought from "OnlineMusicFilmsGames" for £4.98
I do not plan to buy from OMFG again. 2 of the DVD holders were broken off thanks to which the DVDs were free to move inside the box and got scratched up. The plastic bits were not inside meaning it was already broken when they packaged it. Definitely wouldn't call that "Very Good".
I was also meant to get 2001: A space Odyssey collector's edition that was to include a Senitype film cell, but I got a refund with "Out of stock" :(
Currently on the way is Kursk: The last mission.
