What's New?

May 2022

Following the recent increases in Royal Mail postage we have adjusted our P&P charges. These will be shown when you check out.

We now have 3D printed cases for the Pi-SPROG 3 Plus in stock and will add them to the website shortly.

Export Sales

We are now pleased to be able to offer VAT free sales for all export orders, now including the EU following Brexit. Tax free prices should be shown if you are registered and logged in, or at the final checkout page when your shipping address is known. You may still be liable for import taxes and duty in your own country. Please report any issues with prices using our regular e-mail address.


Due to ongoing extended shipping times for International orders, we are now only offering tracked/signed service. This provides reassurance for both ourselves and our customers that orders are in transit. Tracking information will be include in your shipment advice e-mail.

Some deliveries to the EU are experiencing delays either due to Brexit or Covid-19. The Deutsche Post tracking system does not seem to be recognising Royal Mail tracking numbers so it is difficult to track orders to Germany. Some orders have been returned, despite havoing the correct customs paperwork. Please be patient :)

Deliveries to Australia are currently taking approximately one month!

Deliveries to some parts of the UK are still taking longer than normal, so please be patient. All our UK orders are sent as First Class Small Parcel.
