Former Member $organization

We currently have a custom website, and have recently upgraded to V12.5. www.mcfta.org I'm in the process of re-skinning, changing our menus, and implementing a pricing rules box or pop-up. We are looking for examples of how pricing rules display during the checkout process for other organization's website. Would love any examples you could point me to so I have an idea of what to emulate. Thank you!
