Be Excellent To Each Other

Ordered a cheap blu-ray (~£5) a while back and instead Mr. Large-online-retailer has sent me a TV series boxset (~£30).

Where do i stand legally, can I keep it? Can I flog it on eBay? Will my children still visit me in prison?

Additional fact! I've already seen the series so I've no interest in keeping it.

You have to smash it all up and send them proof.

Legally, no you can't, it doesn't come under the unsolicited goods part as you asked for a blu-ray and got sent something that was obviously a mistake.

What Trooper said.

I had a feeling that might be the case, I doubt they'd ever work out I had it but not really worth the the 10 year stretch in Guantanamo for a Blu-ray...

I'd tell them to send me what I ordered and ask them to organise collection for the box set.

They have a good returns system, can print off a pre-paid label and shove it back to them, but the lure of crimes is strong

Send them a ransom note.

If it's amazon, tell them. They'll probably send the one you wanted and say you can keep the box set. They're very good when it's them that made the mistake.

It doesn't sound like its worth keeping so I'd come clean. It'll give you a good feeling inside if nothing else.

I do like a good feeling

Do this, and also ask them to refund the original postage fee for the delay and inconvenience.

Take the discs out and smear excrement in the boxes.

And then keep it all anyway.

Yeah, the right thing to do is to e-mail them and explain. But, after doing so, if they make life difficult for you in any way in terms of returning the item or they do not respond in a reasonable time frame (say, two weeks) then I feel you are within your moral rights to keep it as a 'windfall' item. Life is too short to try and correct an error on the part of some super-mega corp.
