Hello
I've been preparing component lists for several days. I wanted to send the components in the same shipment as the pcb. But after having made the payment of the pcb they warn me that the order exceeds 1.5kg and I must pay at least $ 28.11 for shipping costs (royal mail). I have already paid the expenses of the pcb and the shipment is by standard mail.
I do not recommend this component store. It's a waste of time.
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Hi there,
Actually a reminder of limit weight for Registered Air Mail shipping is provided at JLCPCB checkout page. "Registered Air Mail only support the PCB weight smaller than 1.5KG."
However the reminder may not be obvious but also clear enough. Which we would like to make an improvement in it.
We have to apologize that the FAQ for combined shipping does not clarify the limit weight issue of registered air mail shipping. We've just updated the FAQ for a better guide.
Besides, LCSC will add hints at checkout for each air mail shipping option which has limit weight requirement to avoid causing problems to our customers.
We have provided a solution to you which sent by email. Please check it and we look forward to your reply.
Thanks for your feedbacks to help us doing better here.
