I just had a look, and the pair (Op & Meg) shipped from BBTS comes to US$78 (about AU$74 right now)... and would arrive before most of us end up seeing them in a store near us.
Does Hasbro really think that their sales won't suffer if you can save 25% by importing the exact same product?
Stores here rarely discount that much, to make it worth waiting for a sale either.
