Are goods like Miu Miu, LV expensive?

One of my not so close friends returned from Japan with a lot of handbags but I dare not ask her whether it's fake ones or original. The Dior bags that she has is probably the older version with the words christian dior and not the Alphabet D etc... And she bought YSL, Polo Ralph Lauren and many more.

I wonder are these branded goods that cheap in Tokyo?

I don't know where you are from (what you are comparing against), but I must say branded goods are expensive in Japan - also now with the strong yen, there is no reason to buy in Japan at all.

She possibly went for second-hand goods - pawn shops get pretty new stuff as well as well-used goods - and if she knew where to look, she could have found some bargains there.
