You are so many people to email, so I prefer to write a journal:
I send all people's doujins on friday. I go to the post office every FRIDAY
instead of going to the post office everyday. You should receive it within 7-20 days after I ship them (time will depend on where you are from)
I already sent last friday
all doujins that were paid before June 22th.This friday
I'll send those doujins that were paid since June 22th.
When the doujin arrives to your house successfully, my post office will automatically inform me.
