PK National Eyecare Group - Supporting your Independence Privacy Policy Terms of Use More information You will all be aware of DX; after all they deliver to every Optician in the country and as the courier of choice for just about every supplier in the country. The difficulty has always been when you want to send something back to the supplier, you either have to queue up at the post office or if you could guarantee items every day you have DX do a daily pick up from your practice. Now there is an alternative for practices who only have small numbers of items or don’t need to send items every day. DX Optical Exchange works by using the DX exchange box’s which are spread across the entire UK; most practices are only a few hundred yards from their nearest box. You pay an annual fee that relates to the number of items that you normally send, averaged out over a year, you then simple address the package include your DX details and then drop into your nearest exchange box before 5pm and it will delivered the next day, no queuing, no strikes to contend with and all for less than the post office.
