To export several sets, go to the exporter. If you use the data I'd really appreciate a link back to Brick Insights. It keeps this site going.
Batgirl only appears in three other sets at the moment so there is a fair chance that she will be new to some people. On that basis this is an excellent polybag as the detail of the minifigure is tremendous and if you are intending to purchase The LEGO Batman Movie on DVD or Blu-Ray then this is certainly a nice bonus which is worth a little extra expense.
