Whenever an item that qualifies for free worldwide shipping is added to the cart, Chess.com will add a free beanie. This freebie does not qualify for free shipping, so the whole order doesn't qualify anymore. The item cannot be removed from the cart (at least I didn't see an easy way to do so).
Basically, it's a bug that prevents thousands of people worldwide from shopping from your store.
The site doesn't run the store, that is handled by House of Staunton. There is a chat option on their site; they can probably fix it for you.
