Hi and welcome to the foum

I buy Cubans as I live in the UK and again it all depends. I bought a box of Trinidad Reyes and had one the day i got them. It was an exceptional smoke. Other Cubans though I've had have definitly needed at least a month in the humidor sometimes more. I agree that it depends alot on were they've been stored before and on storage during transit. If buying a box though just try one, if you like it then time in the humidor will just increase the flavours, if not good then give it a few months and try another and so on.
