A while back TL did increase prices in Bakery Story. For more information you can read the below linked thread.
Bakery Increase Prices thread.
These changes will not be reverted at this time and TL believes this is the right decision to improve the game for a long term. If there are changes in the future, TL will visit this topic again and review more feedback.
If you would like to discuss this further, please post a new thread under the
forum and the community managers will address any of your concerns.
