I know someone who had a pair of them stolen from their Prius that was parked at a commuter transit lot. Given Toyota's pricing, and other unknown factors, there is probably a certain unfulfilled demand for them.
The allow wheels they hide actually look pretty good, so the center cap mod is probably the cheapest and best solution if one isn't concerned about any possible effect on fuel economy.
