The Pollinic Girls Attack! Complete has the wrong price listed on the Black Friday 2019 Sale page, is should be the same as Shoujo Material and Non Virgin. And another very tiny problem with those as well - the sale page lists their new prices as $12.48, the store as $12.47.
edit: And as tradition goes, also some wrong links - Black Tights and Black Tights Deep images link respectively to Kira Kira and Whispers After Class.
