It would be great to see non Amazon purchase options. I understand that would increase the complexity and it might make it more difficult to monetize if you want to add affiliate links, but having more options that might better fit a user could give the tool more use.
I would not purchase any of the options suggested to me by your site. With that said, It's also possible I am not your target demographic.
