I bought the LONDON PASS on-line for my London Trip in May 2012.
it was the first time I bought something on the web, and I'm very satisfied of it.
you don't need reservations, you enter first in more attractive places, you don't have to wait more.
I did't do other kind of shopping there so I can't rate if prices are chip or not, or if discounts with London Pass are convenients.
however I rite it like a very good experience that I'll do again!
