>>10270420I recently gave away my LPS fitness center to my cousin's kids. At first I regretted it because of so many memories playing with that set, but then they sent me a video of their daughters playing with it and I felt a lot better (plus the thing was really just taking up space in my room).
OP, I bet you could find random LPS toys if you searched around in charity shops and flea markets, I've found a few older pets that way. Searching for things like this online aren't always the best option because collectors are the ones selling them and assigning value. A grandma at a market stall is going to sell them for 2 dollars apiece regardless of what kind of pet it is. The downside with in-person hunting is that you have to get pretty lucky if you're looking for anything very specific.
