We realize that you might have a good year and surpass your current membership book limit partway through your current membership period. We don’t think it’s fair to make you pay full price for the next upgrade level.
So at any time during the year, authors who are current members can upgrade to the next level for just $20 – the difference in price between levels – for the rest of their term.
Pay by paypal account or credit card.
