I ordered my first set of PCBs from JLCPCB and was very pleased to see how quickly they completed production and posted them.
Now, I opted for a cheapo delivery and so am not expecting too much. I chose "Shipping Method: GB Special Air Mail".
However, when I use their link to track the delivery, the site it gives cannot recognise the carrier from the code number that begins "jjd"!
Any ideas which carrier it is in the UK?
