I have Creamsicle. I do ship worldwide but I am in the United States so of course shipping is going to be a bit higher, especially since shipping prices have raised quite a bit (both domestic and international).
If you're looking for cutesaurus, you're probably going to be paying around $100 on the lower end. She seems to typically be between $100 and $150, but I usually see the ones listed anything above $120 sitting for a very long time.
Oakly is pretty ridiculous price wise in my opinion. I know he isn't the most common pony friend but he also isn't considered rare. I would just say uncommon. But I've seen him selling for $200, which I think is absurd *shrug*
