Maybe a long-shot for a trade here, but what the heck...
I'm looking to pick up retired modulars (2013 and earlier--Palace Cinema, Town Hall, etc.) and/or Winter Village (2015 and earlier--Toy Shop, Santa's Workshop, etc.) I don't have a ton of stuff that I can offer, but I do have a few sets with decent-to-good value. I prefer new in box, but might be willing to negotiate on that.
What I have to offer (all new in sealed box; any box damage I remember off the top of my head is noted, but I can give more detail on a specific set if the box matters; smoke free, but not pet free home):#10246
Detective's Office (thumb-sized dent/hole on the bottom of the box; All cardboard is there, but it's torn in a hole)#77904
Nebulon-B (minor crease on at least two sides of the box. Unfortunately both sets I got had some damage from shipping, I will offer a choice of the 2 if it matters to you)#75294
I also have some promo sets (including Hoth and Endor dioramas, a couple Christmas ones, Diagon Alley, HP Bricktober minifig set) and some retired Brickheadz.
I'll check Bricklink values (6-month sales and current US listings), but certainly don't need it be an exact $1 for $1 trade.
