The best promotional items?

Hi all,

We are launching a new business shortly, and we are weighing in which promotional items (if any) it is worth spending money.

The business is a job search service (like a monster) but specific to the medical industry.

We think that pens are a good idea, since we have heard with good authority that doctors are always looking for and stealing other pens.

But what else? What success have you had with the marketing materials?

When responding, keep in mind our target audience: mainly doctors, often locum doctors in short-term locations. Another key market for us will be the recruitment agencies.

Thank you,
Jason
