i think you can go to Bonjour or Sasa to buy samples.(Bonjour:10g/$35)(Sasa:10g/$42)
if you don't want to buy samples, you can buy the one with normal size. You can get 20% or 30% discount. But I suggest you buy samples as they are more cheaper. One more benefit is that if you buy samples and you don't like the product, you can return it and exchange for the other one(Of course it is only for unopened products & only in Bonjour) If you buy products in normal size, you can't exchange!!
Bonjour and Sasa have many branches in Kowloon, such as Mongkok, Kwun Tong and Kowloon Bay. But you should not go to some branches in TST or Jordan because the samples there would be more expensive( tourists' attractions)
