I'm absolutely clueless about how many stamps I need to put on my SASE for the replay from the USA to Germany (where I live). I plan to buy the american stamps in an internet-shop because I heard that a SASE is better than an International Replay Coupon. But nobody here in Germany can tell me how many of the stamps I will need!!!
This fanmail is very important for me, and I dont't want to loose it in cause of wrong porto

Please help me, I would be very grateful for any answers and advices
