Thanks to everyone interested so far.
For the GameFans and Gamer's Republic shipping would be $2.93 Media Mail. With the EGM2s it goes to $6.08.
For all the ODMs and Nintendo Power shipping is $4.33 Media Mail.
Well, I can use a Priority Mail flat rate box for international shipping. I can put up to 20 pounds in it and the cost is $24.65 regardless. And the weight of the EGM2s is 7lbs and they fill about a third of the box.
For everyone else (international, not Canada) it seems the priority flat rate for up to 20 pounds is $39.85. For an envelope, max 4 pounds is $12.30.
For everyone in the states who might be interested in the Flat rate Priority, it is $9.85, no weight restriction. Flat rate envelope, no weight restrictions, is $4.80. That includes Alaska, Hawaii and U.S territories.
It's funny how you always get second thoughts when you know they are going to go away. At least they'll be going to a good cause. BTW, I'm Dooga from U-G/BitG so drop me a message if anyone has doubts about my legitimacy.
EDIT:
Pics of the magazines everyone has shown an interest in so far:
EDIT 2:
I just realized that the EGM2 pic had three missing and issue number 83 was actually an EGM sorry for the confusion. The other two have been added to the pics and the shipping quotes updated.
