I want to buy several Sourcebooks, but everytime I press the "Place My Order" Button it just stays clicked and nothing happens.

Already cleared my cache and tried doing it after some hours, nothing happens...

Do you have any extensions currently running in your browser? There may be an extension that is preventing that button from working as intended. 

Additionally, ensure that all of the information provided for the address and payment information is consistent with the information your payment provider has for you.
