Comvita UMF 10+ Manuka Honey 500g is selling for 49.99 AUD at (approximately 257 HKD) at ChemistWarehouse, this is way cheaper than HK local seller, HKTVMall, iHerb, etc...

The price is not including delivery fee but they do deliver to Hong Kong.

Last time I order i paid 72 AUD (approximately 370 HKD) for a 4kg parcel delivery.
