The truth about celebrity gift bags

From today’s NYT:

For every success story of an actor posing with a watch, a dozen other companies see their products disappear into limousines, never to be glimpsed in public again. And in the case of the highest-priced items – the trip to Antarctica, the party planning offer – only 5 percent to 10 percent are ever redeemed by the celebrity, Ms. Wood and others in her line of work say.

Won’t more celebrities please go to Antarctica?
