How much Lego???

Lego Imperial Star DestroyerWell, I though it was a bit crazy when Katie’s theatre company paid my mate Dave in Lego for designing their (excellent) website, but a bunch of students (they must have been) leaving the train this evening at Bournville really got me thinking. Between them they were carrying about 6 huge yellow Lego bags and clutching two colossal boxes like the Imperial Star Destroyer that they got Dave. That stuff must have been worth at least a grand? What were they up to? Answers on the back of a post card, or in the comments section, below.
