title: eBay API 'Invalid auction currency' error
body: <p>I'm trying to add eBay listing through their API using SDK (<a href="https://github.com/timotheus/ebaysdk-python" rel="nofollow noreferrer">ebaysdk-python</a>). I run tests on sandbox.ebay.co.uk with Trading API Sandbox.</p>
  
  <p>I am selling my products on eBay.co.uk and I want specify price in GBP. Products are shipped from Poland. With these params I have problem with GBP currency.</p>
  
  <pre><code>item = {
              "Item": {
                  ...
                  "Country": "PL",
                  "Currency": "GBP",
                  "Site": "UK",
                  ...
              }
          }
  
  api.execute('AddItem', item)
  </code></pre>
  
  <p>I'm getting an error:</p>
  
  <pre><code>AddItem: Class: RequestError, Severity: Error, Code: 95, Invalid auction currency. The auction currency specified does not match the auction currency for the selected site.
  </code></pre>
  
  <p>eBay API doc says: 
  <a href="http://developer.ebay.com/DevZone/XML/docs/Reference/ebay/types/SiteCodeType.html" rel="nofollow noreferrer">http://developer.ebay.com/DevZone/XML/docs/Reference/ebay/types/SiteCodeType.html</a>
  so the settings seem to be correct</p>
