  6. RSS version of Deals, Rebates, Coupon Codes

XML Web Services Version 2

We have made some improvements to DFF's XML web services to deliver more data and more accuracy with Version 2.
Version 2 XML web services uses UTF-8 / Unicode character encoding. Version 2 is also more similar structural wise to our JSON web services.
Version 2 is available for Price Search Engine (PSE) and all newer XML web services will all use UTF-8 / Unicode character encoding.
