...when you find out that despite checking and re-checking your order, what turns up are 100 0.1uF 0402 6.3V capacitors and not 100 0.1uF 0805 50V capacitors. 
How does that happen??? It's not so much the cost, as a couple of quid is neither here nor there really, but re-ordering such a small thing will incur handling and delivery charges out of proportion to the item itself.
Anyone need any 0402 capacitors?
