Hello carter. What country are you from? I wish more people would add the location information to their profile. Without this clue in your question I would have assumed you were from the States.

Good question about denominations. I prefer big bills - especially when traveling. In the States our biggest bill is $100. Carrying around a brick of 20s is a pain ;-) - and sometimes that happens - when everyone comes with 20s. Ugh. If were were talking about Euros that's a different animal and would probably want mid sized notes, again $100.
