I'm having another issue, this time relating to a recent component pricing. In EASYEDA, C9864 is priced as $2.41 (per LCSC Electronics).  However, we all know we have to check JLCPCB SMT Part Library, to actually check if items are available for SMT assembly.  In JLCPCB SMT Part Library, C9864 is a basic part, listed at $1.82 (and also in-stock). I selected this component for SMT assembly (and then designed m board around this component). When completed, I exported the Gerber, BOM and PickAndPlace.  The exported BOM now lists this compent as $0.61.  However, when I uploaded the entire project for manufacturing--**I got charged $4.45 for each C9864**.  Obviously at that point, I simply had to pay the inflated price, as I had already designed the my board around this component (and all the supporting components)--and had sunk countless hours into the project. I did attempt to contact customer support, but only got a generic "JLCPCB and LCSC are sister companies."  I also am aware that the market is fluctuating.  However, is there any way for us to know what we're actually going to get charged for a compent, before we spend countless hours designing a project?  Instead of only knowing at the last minute, when we submit for manufacturing? Had I known that the cost of this component is substantially higher than listed, I would have considered the other options (during my initial search of JLCPCB SMT Part Library). Unfortunately, this is the 2nd major issue I've encounter in this single order (a single order that has several separate projects/PCBs)--the first issue is two additional $15 surcharges ($30 total) for two separate panelizations (panelizations that **do follow** all of the posted guidelines).  And I only got hit with the surcharge AFTER I had submitted (and paid) for the order.  Now everything else in that single order is on-hold until I figure out how to deal with the $15 surcharges. Needless to say, this has been rather frustrating--especially to see up-charges and surcharges AFTER I've placed an order (or AFTER I've spent countless hours developing a board).
