Royal Mail workers are going on strike on Friday 26th and Wednesday 31st August. More details here.
Therefore due to the normal bank holiday closure, any orders placed between Thursday 25th and Monday 29th August will be posted on Tuesday 30th August.
This is to prevent any products sitting in the system (or in overflowing post boxes) for too long over the long weekend and potentially getting damaged.
After this any orders will be able to go back to being dispatched within the standard 2 working days, but do be aware that there could be a backlog which slows down delivery for a few days.
