quick question about ordering from btssb?

This is my first time ordering from baby's japanese site I ordered something from their outlet, so sorry if it's a stupid question. I just wanted to ask some of you, how long did it take for them to send you an invoice email? I've received my confirmation, but haven't gotten the email about how much the total cost with shipping will be and how to pay, It's been two days, again sorry for the dumb question, just wanted to get an idea.
