Buying replacement keycaps for the Model 100

I have been a very happy user of a Model 100 for the last couple of years. I was hoping to buy some keycaps (preferably the original set of keycaps that ship with the keyboard or the Mac compatible ones).

I can’t seem to find the original keycaps on the site at all. I can find the Mac keycaps, but the shipping costs are :cry: . If any one has extra keycaps that they don’t mind parting with; I am very interested. (In the US, CA for reference)

Thanks,

Rahul
