As someone who just joined the club a month ago, I can tell you that I have saved over $150 with the ARC discount and I don't even have SW in my tank yet.
It is SO worth it to join the club. The only meeting I have been to was a bit over my head, to say the least, but the knowledgable, friendly, helpful people that make up this club is a wonderful asset and great source of knowledge to learn from.
Also, once you get your tank up and running, the ability to trade things and the kindness of people to give things away to help you get started is awesome.
It is definitely worth it in my opinion.
Also, welcome to the ARC!
