Looking at a AWG-M100SBC-1AJF on Rakuten. This will be my first purchase from Japan, and I've gone ahead and registered on the "fromjapan" site. I've tried to read a ton of stuff about these transactions prior to pulling the trigger, just want to make sure I get it right. Paying with paypal, selected the "check service", "safer domestic shipping" (although free shipping is indicated, I'm guessing that's just inside Japan?). Also not sure if I should select "send it exact packaging". I don't think that's necessary but just a lil nervous newb here.
