$6996.99 per year is $134.56 per week. If you get 5 books per week, that’s $26.91 per book. Given the picture includes a single book costing $19.95, that feels very reasonable. Maybe it’s 6 books a week, maybe some books are more expensive.
That’s a very consistent habit though.
When old testament says to love someone instead of just smiting people, you know that shit is serious.
