title: Get list of ALL offers from Amazon Product Advertising API
body: <p>I need to be able to get a listing of all offers for a product using the amazon API. This is the request I'm sending:</p>
  
  <pre><code>http://webservices.amazon.com/onca/xml?Service=AWSECommerceService&amp;Operation=ItemLookup&amp;SubscriptionId=&amp;AssociateTag=&amp;Version=2011-08-01&amp;ItemId=B007IJQDQQ&amp;IdType=ASIN&amp;ResponseGroup=Offers&amp;Condition=All&amp;MerchantId=All
  </code></pre>
  
  <p>This is returning the follow under offers:</p>
  
  <pre><code>&lt;Offers&gt;
  &lt;TotalOffers&gt;1&lt;/TotalOffers&gt;
  &lt;TotalOfferPages&gt;1&lt;/TotalOfferPages&gt;
  &lt;MoreOffersUrl&gt;

  &lt;/MoreOffersUrl&gt;
  &lt;Offer&gt;
  &lt;OfferAttributes&gt;
  &lt;Condition&gt;New&lt;/Condition&gt;
  &lt;/OfferAttributes&gt;
  &lt;OfferListing&gt;
  &lt;OfferListingId&gt;

  &lt;/OfferListingId&gt;
  &lt;Price&gt;
  &lt;Amount&gt;375&lt;/Amount&gt;
  &lt;CurrencyCode&gt;USD&lt;/CurrencyCode&gt;
  &lt;FormattedPrice&gt;$3.75&lt;/FormattedPrice&gt;
  &lt;/Price&gt;
  &lt;AmountSaved&gt;
  &lt;PercentageSaved&gt;56&lt;/PercentageSaved&gt;
  &lt;Availability&gt;Usually ships in 1-2 business days&lt;/Availability&gt;
  &lt;AvailabilityAttributes&gt;
  &lt;IsEligibleForSuperSaverShipping&gt;0&lt;/IsEligibleForSuperSaverShipping&gt;
  &lt;/OfferListing&gt;
  &lt;/Offer&gt;
  &lt;/Offers&gt;

  <p>As you can see it only returns the 1 offer even though it says there are 3 new offers. Does anyone know of a way to get all the offers and not just the lowest one? Merchant ID='ALL' doesn't do it, neither do any of the other response groups like offerFull, offerSummary, or offers.</p>
