This is an out of production, uncut pattern - the package has slight wear and is priced accordingly. It is from a smoke-free home and shipping is free in the U.S. Please check my other listings - I have a wide range of patterns and will be glad to discount multiple purchases (10% off for two items, 15% off for three items and 20% off for four or more items).
