The Cambio is a small self contained building that I have been using over 15 years...
and it right where I was standing when I took the pic of ValueMaster / NCB ATM photo above........
they are banks.........you can exchange cash or travelers checks at NCB or Scotia but the lines are usually longer than a Cambio
Kone prices are very hard to beat on what they carry..........
it's not a very large store so they must be fairly limited on how much they can carry........
just think of Kones as your local conveince store without the high prices.........
personally I would shop Kone first and what you can't find at Kones I would purchase at ValueMaster as their selection is large and yes the carry larger bottles......
I wouldn't think Kone was in exchange business but they will give change in J's when you purchase something..........
glad mi was some help for you February reach...........mi always learning too........
