When will you restock (x) sealed product?

We are constantly re-ordering items (every week in fact) and looking for new lines to bring in. However due to the nature of the business we are in, the demand for certain products often outstrips the production and we end up waiting for the items to become available with our suppliers. We are given weekly updates as to what is available, but this does mean we often cannot give specific times as to when something will be coming back. Frustrating we know! The other reason that items may be out of stock, and this is most common with our TCG's, is that the set is no longer in print, so it is sometimes worth checking on the internet if that item is still being produced. If it is no longer being printed, we will not be able to order it from our suppliers.
