Has anyone sent this parcel?!

Blip isn't just a photo diary, it's now a lost and found service! So, does anyone recognise this interesting bundle? Contents: 1 dual digital photo frame and 2 pairs of girls' sunglasses.

The box arrived from M&S online a couple of days ago, addressed to us and tagged as a gift. However it had no sender's details or gift message attached and no-one has owned up to it. Suffice to say, we're delighted to be getting such a nice pressie but we're also stumped...
