Well a $50 order still has $10 on shipping for me (from a random order I put together). However, every $10 the order goes up, it costs around $3 less for me to ship.
It would arrive in 3-5 days to the U.S.
I'm actually looking at putting in an option for faster shipping (which would cost money, of course)
EDIT: I have just put in an option for expedited shipping. This is available on checkout!
