Hello Dave,
Thanks for your question about the Amazon plugin being compatible with BoldGrid. BoldGrid is a series of plugins that is specifically made to be compatible to WordPress. We do not test with third-party plugins, so it’s difficult to say if the plugin will be compatible or not. My advice is that since BoldGrid concerns mainly the structures of creating and modifying a website, then it should not conflict with a re-directed link. You are welcome to try it and then check to see if there is a conflict. We have no history of an issue, but you are the first person (to my knowledge) to ask this particular question. If you do run into problems, you are welcome to contact BoldGrid support so that we can investigate the issue in more depth.
