A much needed action for those who like to decorate. A mock house/tower for arranging items that are not available until purchased would certainly turn those "maybes" into "gotta-have-its"! Win-win for everyone!
Maybe a trial period of a few hours or days. Such as "you may try out this ____ for 3 days". Then after that time another pop-up "You have come to the end of your trial period. Would you like to let your trial expire or purchase this item".
