Need help from Hong Kong tFPers!

I'm probably gonna have a trip to Hong Kong in February next year... anybody has an idea of how much the retail prices are for the following items?

1. Trevi PM
2. Koala Wallet
3. Trunks and Bags Key Holder (new release)

THanks :P

does anyone know how much it is in HK or where i can find the price on the internet? thanks.
