I go on vacation to Lancaster, PA several times a year and always go to the Old Country Store. It's a wonderful store that always has lots of people in it and I always come away with goodies. The People's Place Museum is upstairs from the store and although it's a very small museum, it's worth it to go look if you're in the store.
After having been there numerous times over the past 10 years, I can't imagine them not doing right by you. I am not familiar with parcel post, but really hope that your package is caught up in the mail somewhere and it will arrive. If you don't get it soon, I would contact them again.
