From the announcement:
We are celebrating American Independence Day with a big sale on both our 15mm and 25mm Americana buildings. These Items are all pre-painted and assembled ready to put on the table and game. The roofs also come off so you can really get inside your game. Both of these sizes of American buildings will be 25% off of our retail price from now until the 18th of July. You will see the discount on the products when you go to the check out page of the website. This is for a limited time only. All orders over $200 will receive free shipping within the Continental USA (PO Boxes not included). For shipping outside of the USA, please send me an e-mail and I will get you a quote.
