I've literally just been going through all of my still sealed figures and displaying them. I kind of forgot how many I actually had and the 3 DF120's I had delivered 3 years ago aren't even going to be enough space for them all
I should probably take that as a sign and quit with the collecting. I only have a few on preorder right now, but still have my eye on several that I've wanted for years (T-1000, Walking Dead, Daenerys)
I find selling stuff off is a pain in the butt with scams and such. However, I might need to sell off some of my duplicate characters at some stage.
The price has been getting out of hand for the last couple of years. Most figures are around $450 in Australia these days. You can get discounts, but when I think back to them being under $300 before the discount, it really is becoming too expensive to collect these. You can get some figures on great discounts after time and I've waited to pick some up saving quite a bit of money.
I try not to preorder too much these days because the hype wears off and the interest wanes. I didn't end up picking up any of the Spiderman Far From Home figures and I was initially going to get all of those.
InArt's stuff is just getting beyond what I really want to pay for 1/6.
