Pay Once, Pay Twice

Diamonds are a player's best friend. You use them to purchase premium outfits, premium scenes, and collectibles. Depending on the books, characters, and items, some purchases fall under a "one time and done" deal while other purchases fall under a "pay twice or more" every time you replay. This is a list of series and books and their respective scenes and items that fall under one of these two groups.

If you discover a "Pay Twice" or more choice, feel free to use the thumb tack template: to mark the walkthrough where it occurs.

The general rules for premium purchases are:
 * Premium Outfits and Hairstyles: Once purchased, the player may continue to use and reuse premium outfits and hairstyles. However,
 * Male vs Female Outfits: In gender of choice books and series, purchases made for one gender usually do not transfer over if the player replays with the other gender. Also, in books and series where love interests are gender customizable, purchasing an outfit for one gender will not transfer over to the same love interest if you change his/her gender on a replay.
 * Premium Scenes: Once purchased, the player may play and replay premium scenes without needing to purchase again. However,
 * Premium Scenes are "Pay per Love Interest": If your character is not in a committed (engaged to be married) relationship with a Love Interest (which generally happens at the end of Book 2 or the beginning of Book 3), the player pays per love interest.

Exceptions to these rules are listed with the series/books below. If there is nothing listed, the series/book has not been "tested". Editors are welcome to add their observations to the list.
