title: Can I achieve a groupon / kickstarter like payment system with paypal uk
body: <p>I.e. user clicks buy, I authorize their card and wait 2 weeks and see if enough users have pre ordered a given product before charging them and shipping.</p>
  
  <p>I'd like the following - </p>
  
  <ul>
  <li>To avoid pci compliance I'd prefer to whisk users off to paypal for getting c.c. details.</li>
  <li>progmatically reauthorizing any preorders and capturing funds is fine after 2 weeks. But for my prototype doing this via the paypal account dashboard is fine.</li>
  <li>my app being notified when a user successfully preorders (ie. there card is authorized by paypal) in order to update my "preorder" counter on the site.</li>
  </ul>
  
  <p>For my prototype I want to avoid as much coding on this so offloading as much as possible to paypal, even if it means I have to manually handle reauthorizations and payment captures is actually better in the short term.</p>
  
  <p>Can paypal uk provide this functionality and if so which business solution is this? standard or pro?</p>
