I've just finished dealing with DigiKey's export division, and I wonder if anyone else has a similar experience?
I ordered some fairly innocuous parts (a few AVR's, CPLD's, monolithic audio amplifiers, etc) in the evening so that the order would hopefully go through at the start of the US day. Checking back in the morning I find they've held the order and want to know exactly what I'll be doing with the parts before they'll ship them--they weren't satisfied with the answers I gave in the order process.
They also wanted to know if the word "Bit" in my business name was an acronym (it isn't, it refers to a computer bit).
If this was a specific requirement put on them by the US Government I'd be more understanding, but no other US electronics exporter seems to do it (Mouser in particular doesn't).
I don't imagine illegal arms manufacturers have any qualms about lying on a web form or e-mail.
