Here are the bestselling HD Radios on Amazon.com.
In the Amazon category of “radios” I could not find an HD radio at all in the top-100 sellers (did I miss it?), although I found plenty of shower radios and retro radios and clock radios and radios designed to work with mp3 players.
For the Boston Acoustics Receptor HD radio, its sales rank on Amazon is 4,243 (as of today) meaning that there are more than 4,000 electronics items which outsell it at Amazon.
UPDATE: These rankings change all the time. By day’s end, things have improved: The radio’s rank in the electronics category was up to 2,156 and there were 40 radios selling better at Amazon – none of them of the HD variety.
