Online purchasing - hard?

Sometimes I'm amazed by how some people just can't get the online purchasing experience right. Today I was renewing my IEEE membership and... It was hard! They pre-set everything that is in your current membership and then they have this "promotions" page that for each entry and sub-entry, there is a potential dropdown box (that is actually a popup) to let you choose promotions that are relevant to your purchase item. However, I think they forgot to include the manual on what each promotion means. For example (unfortunately I have finished the process already and I didn't really capture a real example):

By my IEEE Computer Society membership, when I opened the promotion popup I received a list that looked like this:

Name - Description
ACM-CS - ACM for CS
JJ-994M -
JJ-98B -
ABC-09 -

Huh?

Anyway, I just gave up on trying any of their promotions and checked out with exactly the same I currently have: IEEE Computer Society, IEEE Intelligent Systems Society, print version of the Transaction of Knowledge and Data Engineering and the Intelligent Systems Magazine.

I haven't been reading papers lately as much as I did in the past, but I still do from time to time. So, I'll stick around until maybe I decide that I'll become poor and buy a house, then I won't be able to spend $600 on that any more.
