I've seen several mentions of Penzey's Spices on this list and want to tell you about another mail order spice place in Australia (prices in Oz $)
I first heard about (and ordered from) Herbie's Spices about 3 years ago. They have EVERYTHING!
Corianders seeds, leaves, ground from India and Australia
Chinese brown and green cardomom pods
Indian brown and green and black cardomom pods
Thai cardomom pods
They have dukkah (delicious Egyptian spice mix used to dip bread - I actually make my own now, but their is very good)
They also have all kinds of unusual seasoning mixes - ground herbs and spices
They have a huge inventory of Indian and Thai spice mixes and curries.
They have dried kaffir lime leaves and curry leaves.
It's fabulous...just fun to look around.
I love the place.
