The LPS inflation is real :((

Like I went on “Marktplaats” (local Dutch online thrift shop) because none of the toy shops here are selling them. And when I found 2 rlly cute ones the person selling them told me they were 13 EUROS. And whats worse is that they are second-hand/used, why is she making it so expensive? 

But it’s not like I can broaden my collection anywhere else  

How is your situation with LPS? How do you guys get your hands on new ones/broaden your collection?
