I'm looking to implement a membership aspect for my website. Basically I want it to give users the option to sign up for a membership card that gives discounts on events I set up. I need it to ask for shipping/address details as well as children/family members and handle payments.
I tried a few wordpress plugins but they all seemed to be lacking in different ways. At this point I really don't care if it's a wordpress plugin, a script, or even an external website.
