Poipet in detail
The faster you get used to making quick conversions between Cambodian riel, US dollars and Thai baht, all of which are in use here, the easier it'll be. A good rule of thumb is 4000r = US$1 = 30B.
Don’t change money at the places suggested by touts, no matter how official they look. In fact, there’s no need to change money at all, as baht work just fine here.
