Hi there, We've checked with your componets order and found the total weight is over 2kg which is unavailable to support free shipping combined with PCB order. There is a shipping notice when the order weight is over 1kg, screenshot as below.  We are going to combine the shipment for you manually. However an extra shipping fee for continued weight is necessary which we will deduct it from the freight you paid for the order 20180403CJQ6, ok? For further confirmation we will reply your email. Thanks. LCSC Support Team

Thanks a lot for explanation! I already paid for shipment from LCSC, and paid for PCBs as well. Good lesson to learn. Based on my calculations I could've split my PCB order by two separate transactions and add parts to one of them, and actually save money overall, even though it looks a bit odd. Let's keep things as they are for now (unless you have a better idea - I need these components together with the board), and I will pay more attention in a future - things that you explained were not obvious during the process because red colored text refers to components, not PCBs (three small bags with resistors and capacitors can't possibly weight > 2kg, and statement supposed to refer to PCBs and components weight combined). What I do not understand is why charges for components shipment are higher than charges for PCBs shipment? It kind of does not make much sense to me. Can you explain?

@alftel Indeed the text is not very obvious to explain why the combined shipping is not available. We will make an improvement on it. We just checked the weight for each item and found LCSC part # C170108 shows the wrong weight for 1g while the other similar capacitor is only 0.028g. Sorry for the mistake. We just fixed the issue. So the total weight of your components order is actually less than 1kg. We will refund the shipping fee $47.2 to your account and arrange to ship it together with your PCB order. LCSC Support Team

Thanks a bunch!

Hello, Just ran again into identical problem when x3 1K resistors were shown as > 1kg and disallowed me to add to today's PCB order. Can you please fix it again? It is definitely another error in your database (I already paid for both orders) My PCB order is [Y23-2060703A and parts order is](javascript:onShowDetail('ced38f3ac6b44fd19a006f868c092bd3',1);)[20180420ND0P](https://lcsc.com/user/orders/20180420ND0P/detail)

Hi Alexander, Thanks for your feedbacks on the parts weight issue. We are checking on it. We notice you placed three components orders today. For your another two orders, 201804205X5V and 20180420DC1Q, we would like to confirm if you had problems with combined shipping also because you chose independent DHL shipping for each order. We will arrange to ship your parts order 20180420ND0P together with PCB order Y23-2060703A, and refund the shipping fee. By the way, please send email to [support@lcsc.com](mailto:support@lcsc.com) directly next time when you have any question related to orders. Thanks. LCSC Support Team
