I'm considering getting the privilege for one of the books I'm reading but I'm really put off by the duration. If I'm reading it correctly, it's suppose to only last till the end of each calendar month? So if I buy it any day past the 1st of each month, I'm basically losing out since the cost doesn't change
Instead of having the privilege duration be by the calendar month, can we pls have it as a fixed value 30days 
It would make it fairer to users since the cost of the privilege is fixed
