Just a note here....even if it isn't a scam (which it is, because as Connie said, it is illegal to ship birds from Cameroon to US/Canada, AND, to have any bird shipped into the US or Canada from anywhere other then US or Canada, you are looking at a pile of paperwork and months of waiting time), anyways, even if it isn't a scam, remember, you get what you pay for. Anyone who is selling a bird to a total stranger for dramatically less then what it is worth, is more likely selling you a very sick bird. People are not going to take that much of a price cut for no reason.
Usually if it is too good to be true, then it probably is.
