A few times I've seen posts bemoaning the fact that offers were valid for USA residents only.
Here's a company that knows how to do it right. An excerpt from their last newsletter:
Yes, you heard it right. Despair, Inc. is extending to our domestic
customers a special father's day coupon code, granting the American
user TOTALLY FREE SHIPPING on all orders over $15*. All you
have to do to get it is to be willing to type in the following
coupon code: "yesasamatteroffactireallyamthischeap" (NO QUOTES).
(OR, if you're just as lazy as you are stingy, "imcheap" works, too, but
man, I just have to let you know that if you type this in, you are so not
the kind of customer that marketing people want to target. Just so we
understand each other.)
Yes, those of you outside the United States are excluded from this
promotion. But because we feel sorry for you, we are offering an
alternate coupon code, which will grant the user 15% off their order.
All you have to do is type, "iwishilivedinamerica"(NO QUOTES).
The company is despair.com, and they're right into the art of DEmotivation. Worth a look.
