Penzey’s has something on their Facebook page. Apparently the response to their free box of spices was overwhelming. They have run out of the jars, but they are working on it. The jars should be in stock next week and they are working on getting all of the offers filled.
Sorry about this guys, but it sounds like Penzey’s is working on fulfilling orders. I guess April is their slowest month and they were caught unaware of the response.
