title: Paypal Website Payments Standard with a Ruby/Rails application
body: <p>I would like to implement a payment solution with my Rails site using Paypal Website Payments Standard. (See <a href="https://www.paypal.com/IntegrationCenter/ic_standard_home.html" rel="noreferrer">https://www.paypal.com/IntegrationCenter/ic_standard_home.html</a>). I don't want fancy gateways, and I don't want to go through the hassles related to storing credit card information. I also want to use Paypal IPN for notifications. </p>
  
  <p>I have checked out various sites such as <a href="http://www.fortytwo.gr/blog/14/Using-Paypal-with-Rails" rel="noreferrer">http://www.fortytwo.gr/blog/14/Using-Paypal-with-Rails</a>, and I'm too cheap to try Rails Kits at <a href="http://railskits.com/saas/" rel="noreferrer">http://railskits.com/saas/</a>. </p>
  
  <p>Does anybody know of a working open-source Rails application that makes use of Paypal Website Payments Standard for billing, and can you point me to that code?</p>
  
  <p>Also, my business is in Canada, but the servers are in the USA. Do I have to sign up for Paypal.com or paypal.ca?</p>
