buy from where???
and what u spend on other than temple pass, food and transport???
^ You mean the coffee ?
There are a lot of places to buy the coffee beans, but I would recommend Asia Market.
It is technically not a market, despite the name, lol. It is like a mini-mart, situated in Phnom Penh (nearby Pub Street).
Temple pass :
USD20/day pass at Siem Reap.
I didn't go to visit the Killing Fields in Phonm Penh (I think it is priced at USD30/day pass).
Food :
As for breakfast, I ate at the hotel (I selected hotels that includes breakfast.
For lunch/dinner, I opted to eat at the roadstalls, as opposed to established eateries). +-USD15/day.
Transport :
Tuk-tuks all the way. Have to pandai negotiate a bit, as they will ask for higher sum initially.
Actually, no need to pandai sangat oso can, as you can say no, and proceed to hitch another tuk-tuk with cheaper fare.
Hope this helps
