Sometimes the supermarkets can change their distrubution or be out of stock of certain products due to a number of reasons. You can ask your local store for more detail on whether they stock certain items.
First of all, that's sad. If you have a faulty product from in store, you can contact us at email@example.com and we will arrange a replacement for you. Alternatively, you can take this back to the store you purchased it from for an exchange or a refund.
