Good morning Gina,
There is no UP source for nucs,queens or packages. That said, you might sporadically find a nuc that someone wants to sell if they split a hive--late spring or early summer. Same goes for queens--there are some that breed some of their own in mid summer and have a couple to spare. Unfortunately, there is no one that does this as a business. Our local club puts in a joint order for packages that usually arrive in the last part of April. Keep you your eye on the club page for info regarding this process.
