A words puzzle

[blimix]

Entertaining myself during a ride, I wondered whether I could think of any triple homophones: Sets of three identical sounding words, all spelled differently. (e.g., rays / raze / raise.) I started a list, and came up with fourteen sets. How many can you think of?

(Of course other people have thought of this too, so no web searches! Comments are screened, so you can post your answers if you like.)
