I checked a few shops today and my 'reseach findings" are as follows:
1. Price of 4oz bottle is the same as 8oz
2. Frankie Materlity (distributor in HK): HK$75 no discount
3. Jusco (Kornhill): same price but 20% off until Sun. 8oz bottle is out of stock
4. Seiyu: 5% for Seiyu card holder and 10% off for TamTam card holders
5. BeBe Dream: HK$215 for three (value pack); 5% off for BeBe Dream card holder
