Vibrator Sale at Amazon.com!

Crazy me, I spend all my Amazon time cruising for books when they are having a vibrator sale!  Or as they would say, personal vibrating massager sale!  What I don't understand is how they can pass off dildos as "non-vibrating personal massagers".  If I want my back massaged, I'm not going to do it with a purple rubber penis.

And if you check out that page, explain to me the presence of the rubber duckie?  It's like vibrator, vibrator, vibrator, rubber duckie, vibrator, vibrator.  Am I missing something?

ETA: Thanks to tezzkatt for pointing out that, yes, the rubber duckie is a vibrator.
