Many people (including me) join Stampin Up to get the best quality product at a discount. I've been a Demonstrator for over 8 years now, and have had lots of fun doing what I do. I've not found it difficult to meet the minimum required to maintain my status, and I enjoy getting together with friends and new people to share ideas and create things. I'm also a member of a couple of private Facebook Groups with other Demonstrators and we get to share more ideas.
For the month of June 2015 only, Stampin Up is offering 2 free stamp sets when you join. You still can choose the content of your starter kit, which has a retail value of $235 for just $169.
The quickest and easiest way to join is online, and you can do so HERE.
