We were always AABB accredited. That requires a facility representative. That was always me. That gave me the equivalent of individual access. In fact, it was not possible (well everything is possible) to have an individual membership if you are also the site representative.
They do have a best practices sections, which is great. We also have a document library here, and members here are always willing to share their ideas on topics, if not their actual SOPs, just ask.
You do get a discount on their books like Standards and the Technical Manual. With your membership, you also get a monthly subscription to Transfusion.
I used their mentorship program after being in the filed for over 25 years. I got a new position, and the mentor they assigned me was wonderful. We talked through a lot of challenging situations I was facing.
There are other sections of their site that become unlocked.
Is it worth it, that's up to you.
