Ask HN: Swag on a budget?

Can anyone suggest good sources of branded swag (giveaway stuff) for a startup on a budget, for someone ordering less than a hundred? Ideally this would bee geek targeted swag, and easy to ship across the Canada/US border.

Or even better... is there such a thing as swag on demand? I upload my logo design, and place drop-ship orders one at a time to send to people?
