Best thing to do is set up an account and build a wish list. That way orders are configured and can move quickly to the cart. That way you won't panic and miss a juice or the configuration you want.
Would recommend providing feedback when they ask. They will build a profile around your preferences if you want. That way you get a custom juice configured just for you.
Last time I looked they typically open 10-10:30 Central and close when they hit capacity. Can vary by day of week and time of year. They usually post anything out of the ordinary on their site.
Good luck, Hope you like them as much as I do.
Got my order in this AM and very excited to try something new. I guess it's a good thing for me and my wallet they only allow orders of five juices or less...I had ten picked out.
