I've got bees from 3 different places and used this method. If the package is too tall (mine weren't), just put an empty super on. I put one on anyway because I put a boardman type feeder on top of frames so they can feed without being robbed. You take the package out the next day. If there are any bees still in it, just sit it in front of the hive and they will go into the hive.
It's easy and no stress on me or the bees.
