I have ordered a Vocal or Instrument Backing Track and I need a Niestandardowy podkład MP3

You can add to your cart the Niestandardowy podkład MP3 you have already ordered in MP3 format, and pay only the remaining amount..

To do this, you must enter the code "UP" in the checkout.

Be careful not to validate your payment if you don't see the discount applied to your order total.
