Sometimes the Daily Deals go on breaks (such as the Christmas holidays). Break duration differs by country. In such case, the live eBay web page should explain the details, while the XML feeds may just be empty (XML coding tip: be prepared for missing fields/nodes).
The feeds above may also contain additional specials that are peripheral to the core Deals.
Sometimes the number of Deals changes for certain promotions or seasons.
The branding above may have changed for some countries (like Germany).
Historically, the XML feeds for DE and UK follow the same schema. I think AU may follow US as well -- but I haven't checked any of this recently.
