They come in $1, $5, and $10. This year Donald is on the $10 - I don't buy the smaller bills because you get "real money" as change so that way I am sure to use them all on my trip and not have to worry about changing them out if I come back with money. Then I don't have to worry about keeping up the receipt too - you can change them out for real money with your receipt but only with a receipt. So I just make sure I use them all.
