That's bullshit. No way that bit of consumer law can be brought to bare on this case. Any court would find in favour of Zavvi and require the customer to return the Vita, or pay for it. The important legal point here is that Zavvi sent out an email saying they sent the Vita in error and would like it back please. That means it was not sent as nor intended to be an unsolicited provision of goods, for which payment would be subsequently demanded.
If Zavvi had said (or included as a little note in the package): "Here we've sent you this nice shiny PS Vita, if you like it please send payment to... or kindly return it in this self addressed courier pack."
There is simply no way that bit of law can be used to justify keeping something that was sent to you in error.
Zavvi might be being dicks about how they are trying to retrieve the Vitas, but the law actually is on their side in that the Vitas do not legitimately belong to those people and they should be returned to Zavvi.
