I don't think Farnell is wrong on this. But your request likely need at least a manager or above to override as they would not be able to square the differences in their account. This shall be a big problem to their department and auditor. You shall have to ask to speak to higher level if you want it adjusted. Farnell is E14 here (Singapore). They are not competitive, their price is higher by quite a bit compare to Mouser or Digikey, and range smallers, and delivery is longer if I put in a local for Thursday or Friday than an order to the US. Lately, they didnt get to process my order for 10 days, I got to call to remind them, and after they could not bill as there was some problem with their system. So they could not send because they could not bill, and so more wasted time.
