Why can‘t I activate my license/promo code?

I have tried to activate my copy of PDF Expert with the promo code/license code I received and I've never been able to do so.


  1. Copy your promo code for PDF Expert: STCKCOM-** OR INTSUP-**
  2. Open Readdle Store https://pdfexpert.com/store 
  3. Click Proceed to checkout -> click Enter Promotional Code
  4. Paste your code and click Apply
  5. Fill out the fields -> Place your order
  6. Download PDF Expert for Mac and use the license code you'll receive via email
