Libertas Academica offers a 20% discount for authors publishing a second paper in the same journal in the same year. In their words:
Discounts for former authors: Authors who have published a paper in the past 12 months and paid an undiscounted fee may receive a 20% discount on the full fee of their next paper. Authors must complete an application and receive an email confirming application acceptance before manuscript submission.

The following language from the International Journal of Innovative Research and Development makes it easy to picture the author negotiations that must have led to this FAQ. It’s also a good example of something I’ve just noticed this year, a loyalty discount for authors publishing more than one paper in the same journal. I’ll add another column to our list of variations for the loyalty discount.
IS THE PUBLICATION FEE NEGOTIABLE??
No, the publication fee is fixed.
DO YOU OFFER ANY DISCOUNT??
If yes, what is the condition for availing a discount?
Yes, we give a discount of 10%.
In this case, the contributing author has to publish two papers in two consecutive issues (conforming to all the norms of the IJIRD) without availing the IJIRD membership program. When for the third time he/she will publish his/her paper, will unquestionably get a reduction of 10%.
NB: In this case the concerned author has to be one of the contributors and declare his copyrights in all particulars.
