After the last post about why MAA would have very retarded stuff on it's undergrad sign up site and sending them a mail notify about it. MAA finally fixed it's error. Few days ago the online membership sign up was offline, maybe that's when they did the update.

Now there is not way to exploit.
There is no way to get all the journals with discount either.

I'm not an MAA member because their website just filled with bugs. Registration proved to be impossible. Really just get Drupal and stop hire noob to create your website. Be more like AMS please!

Update:
It worked now.
but still.
Get real developers to do the job.

MAA, Mathematical Association of America has a very strange price system.
Let's take a look on how to get the journals(if you are a undergraduate) from MAA pay the least price(if you can get enough people to help you.)
The kind of memberships:

Seriously. WTF.
Get a
student membership + math horizon = 30
student membership + College mathematics journal = 30
but student membership + College mathematics journal + math horizon = 67.

So MAA might have people who are good at math but seriously doesn't get marketing, or they just want people who suck at math pay more price.

Only $80 is required to get all four journals, while if you select that choice, it is $161
