Most of our products and some publications in large print (16 point and above) can be sent by freepost under the 'Articles for the Blind' scheme.

When we send your products, the package will include a 'dispatch note' with details of the contents. It is really important to check this against the actual contents of the package and alert us immediately (within 7 working days) of receiving the order about any discrepancies.
