If u dont bring ur own stationanry, envelopes and stamps for letters, then do they give u some or do they have some for u to buy?

You can buy stuff like that in the exchange but it is probably far easier to carry it with you. Your time in the exchange, from what I have heard, is rather hustled and you won't have time to stroll along and shop. Just a thought, hit Walmart tonight!

Everyone says that having them pre-addressed helps a lot as well.

get staitionary before you get there, and stamps. and make sure you bring enough becasue I ran out and leaned on my shipmates to get some more. my mom gave out pre addressed envelopes to the rest of my family. I wish I made some up myself to bring with me.
