Apologies, we are having a few issues with the website at the moment meaning you may not be able to add certain products to your cart.
The bug was due to an auto-update on the product option ‘plug-in’ meaning it only effects products that have options on them. Any product without an option can be added to the cart.
We hope the company who produce this ‘plug-in’ will sort it asap, but it may not happen until Monday.
Apologies for any inconvenience.
