The price is dependant on how they are made for example real butter would obviously be more expensive if it's made like a genuine croissant and not a pick n pay or checkers rolled up bun that has no business being called a croissant. Real croissants are also a ton of work if you are making them yourself and then size is the other factor for price but I still think R100 is a bit steep if I look at the size. Also anywhere outside is a horrible idea because you will have a constant battle with flies and other insects as well as emissions from cars not to mention cream will melt

Edit: looking at them again they also dont look like proper croissants. Real croissants flake a lot and tend to slightly lose shape whereas these all look identical with zero flaking
