In the past couple of days, I received a PDF of a QSL.  However, that QSL was accompanied with a note explaining that they were sending a card out via buro, using URE’s QD-URE service (create QSL designs on their site, upload ADIF files, and they print, sort, and ship the cards out for you).

One of the things the QD-URE service permits is downloading PDFs of the QSL cards that will be generated.  It’s a nifty feature, especially if you’re looking for confirmation that your custom QSL design actually works.  :)
