> Because the cost of someone picking up a reel of 10000 resistors, from a warehouse that has to be rented heated/cooled etc etc doesn't scale down to that 1 resistor

I understand that. But please charge me for what it costs. Don't let people with small orders pay the price for people with large orders. They already get discount for their order size!

Or if this is not possible at least call it an order-picking fee, don't lump it in the shipping costs.
