I went down the rabbit hole of slipcover collecting and steelbooks many years ago and would buy films just for the slip or because it was a steelbook.
It was actually this forum that got me into steelbooks, someone had the Canadian Pirates of the Caribbean steelbooks for sale and instantly I was hooked
Now I bin most slipcovers and don't really care if there's one when I buy a movie.
I'd often buy films I didn't like because it was a steelbook.
It even got to the point where I'd buy the steelbook but keep it sealed and buy an amaray to watch which needed a slipcover
Then it was two steelbooks, one I could open and one I'd keep sealed.
I was in a very well paid job and had far too much money to waste and often got bored with collecting, I don't drink or smoke so felt I may as well spend extra income on movies.
Sold my collection twice and currently in the process of kind of selling for a third time, but still have around 1500 steelbooks that'll never see the light of day. Occasionally I'll trade some in at the local CEX but only when prices are good enough.
Since moving 90% of what collection I have left remains in boxes much to the annoyance of my wife.
I did have a purge and take several boxes of slipcovers and J cards for the steelbooks to the recycling centre when I moved.
Now I buy movies on digital so tend to not have the issue of buying for the sake of it being in a steelbook or having a slipcover although I do tend to find myself buying a film as it's on offer that I'll probably never watch
