This is all very funny stuff you guys are spotting... I appreciate them, as I'm sure do GH's other, lurky non-bargain appreciators.
And we are just passionate people about a passionate subject, and while we are discussing the subject, we are using the subject in question to discuss aforementioned subject. Now tell me what the subject of that sentence was.
We're already using keebs to discuss keebs, a kind of circular logic—so anything beyond that would be right at home in M. C. Escher-land:
A single blue keycap from a PFU Color key set....
IIRC, a whole set of 4 caps and a puller is just $22....
This is $15?

Yeah, Topre-compatible keys are always goofy-pricey. No doubt vendors figure, "These people spent at least $200 on their keebs [although they may not use that particular term] and obviously have more money than they can spend... What's another $15 for a colored Esc key?"
BTW, I'm gratified to see we're finally starting to refer to these as
keys rather than
caps (a KB term IBM invented for their two piece keys consisting of
stems and
caps). Historically, KB-makers have also referred to them as
buttons, because they were square, and thus had the same aspect ratio as round
buttons on control panels—as opposed to, say, piano keys.
And in case you wondered: A typewriter
key consists of a
button and a control rod.
"Parts is parts", as they say in the industry... Separate, specific names for things is good.
But I digress.
