I bought at harrods, midium size is around hk$150 at that time (I think). No time to buy at the airport la.....it takes time to pick ma & it also takes time to get the tax return......& if you buy at the airport, you will have to hand carry them wor. I didn't check around in the airport, but there are many different patterns at harrod's......all around the entire department store at different departments.....I don't think there can be as many in the airport la.
