The SHOP regularly pulls items from a long list of Crowns Only items and displays them in the ‘On Sale’ section. These items will differ from character to character, and even differ between characters on the same account. An item may be ‘On Sale’ for a day, or a week.
Thank you for the answer. I was really looking for whether specifically the houses will end up on sale again. When you said a long list of "crowns only" items, I now wonder if that excludes items that you can purchase with crowns AND gold because if so, wouldn't that actually exclude the houses?
Sorry to be asking for more details but it is a matter of waiting for a specific house to go on sale before purchasing it and knowing if that would be a fruitless endeavor.
