I am going to the US Next year and need to change some money to dollars obviously.
However, I want to know is there anywhere I can purchase dollars online that allow me to choose all or some of the denominations?
ie. I purchase $100 and get eg; 3 x $20 6 x $5.
The only reason being obviously need some lower denominations for tips and all the currency places in town only have $10 and up..
