Where to buy Foiled Chocolate in Sydney?

Hi guys, i'm travelling overseas and want to buy some chocolates as gifts. I want to buy the small packs (bite size) pure chocolate that wrapped in foil but couldn't find it at Coles or other popular supermarket, all i found is the big bar size which is not what i'm after. Do you know where to buy those foiled chocolates in Sydney at the best prices? Thanks a lot.
