title: Facebook dynamic ads - product feed issue
body: <p>I am currently trying to set up a product feed for Facebook dynamic ads, but the system keeps saying saying there is an error with "incorrectly formatted shipping". However, it is the same XML feed which I use in Google Merchant Center for Google Shopping ads (where it works with no issues). And it should be officially supported by Facebook as well.</p>
  
  <p>This is how my shipping is formatted: <b>CZ::Česká pošta - Balík do ruky:77,00</b>
  <br/>Is the problem with two colons in a row? Or what else should I correct?</p>
  
  <p>Thanks in advance,
  Hoang.</p>
