Price Drops is a new mod that has been updated to work with the new version of SMAPI.

If you have a good and positive relationship with shop owners, you can now get discounts that come in three varieties: 10% at three hearts, 25% at seven hearts, and 50% at ten hearts. The discount percentages correspond to each other, so you can set the value of your discount as you wish.

A new option has been added to the mod, allowing you to add the name of a custom NPC to the configuration file. The shop owner must be an NPC with which you can earn hearts.
