Basically just buy two padded envelopes big enough for the magazine. Address one to the player and inside of that one put the magazine, I usually put a letter of request, and then the return envelope addressed to you. For postage, you can just use stamps or have the post office weigh it for you. This was the first time I sent a magazine so I wasn't sure on postage, so I just used what I would use for a baseball, which is 6 stamps. That may have be overkill, I don't know. Just mail to Nyjer Morgan c/o Milwaukee Brewers Miller Park One Brewers Way Milwaukee, WI (can't remember zip) Let me know if this doesn't make sense or you need more help. Good Luck
