Just leave em in the bag they came in if you must. They survived transit in the mail, they'll survive one more day. The best thing to do is just dump em in a bucket of water strait out the tap. I often do this when trimming plants. I cut out a bunch, put it in a bucket of water with no light, declorinator or anything else. Sometimes I wait and see if anybody wants any. Usually i bag them up and throw them away after a week. It still good after a week just sitting in a bucket like that.
Ok I see you're already back. In the furture I would put em in a bucket of water. It'll be good for over a week.
