I rarely ship international. I used to routinely ship packages overseas, but after I got the short end of the stick twice (both times to France) along with having to deal with some really rude French pricks, I no longer offer overseas shipping unless the package is an insured MFRB. A SFRB doesn't offer insurance for international shipments, and I won't use them, no matter how many or how few chips are involved. Most buyers don't want to pay the extra shipping costs and taxes (since there's a declared value), and that's fine with me -- less hassle I spend filling out PITA custom forms.
I do make exceptions for overseas buyers that I know well, or those I have bought from before (returning the favor). And I typically don't consider Canadian shipments as international (even though they do require customs form) - hey, they're neighbors.
