Great, now the lines at Heathrow will be even longer as we wait for kids to eat all their duty free candy before embarking due to the new inflight banning of all SUGAR!

There was a shop earlier this year in Wollongong, Australia with the same sort of things.
Including an AWESOME 8ft Predator in the same style.

pics a mate of mine posted in his LJ here:

Some workmates and I went in to the shop after seeing that post, and the shopkeep said that apparently they are sourced from someone in Thailand who makes them.
the Predator was pushing $10,000 pricetag.

Just after these pics were taken they also got an immense throne with an huge eagle over it like a canopy, all done in similar style but skulls etc. And also had a large (6ft) samurai and as you can see in the pic a bunch of smaller aliens, predators and even Gremlins.
