I bought the https://www.renderosity.com/marketplace/products/170311/samant-christmas-book-cafe today because I have been waiting for the price to drop. It does not take a bunch of customizing to get it non-Christmasy. In fact, I did it in less than 5 minutes. Selected and deleted all of the Christmas decorations and now it looks like a plain bookstore. Screen shot below of image that is not rendred.
