Questionable prices on Onyx covers

I have a Poke3, Poke5 and "Go6" (a/k/a Poke6). Each was bought as a package with the matching dark cover. The Poke3 is not magnetic. You can see that the current prices for the Poke5 and Go6 covers are $25 and $40 respectively.

Since I have converted both my Poke5 and Go6 covers to be "backless" and have fine-tuned the device internal magnets I can say with authority that these two covers are identical.

So where does Onyx get off scalping $40 for the "new" cover?
