Shipping Sounds Too Good To Be True?

I have found someone willing to ship me a certain brand of headphones.

They are offering me one unit for $55 plus $28 shipping.

However, for five units the shipping is free.

I have a really bad feeling about this.

Are such offers common?

As it feels like they are offering the free shipping on a number of units which is tempting enough to not care about the risks. Instead of working up from 1 unit to 2 to 3 etc you go from 1 to 5.

All payment through Paypal and my credit card if that helps and I have seen pictures of the headphones on a webcam by the company so they definately have them.

They are fake too if that means anything.

Any adivce.

What's wrong with that?

That's a legitimate offer to me

That sounds like normal business to me too. Quantity purchases get a discount somewhere, nothing new there.

Ah k thanks everyone. Well one package has been shipped the other has not been shipped as customs would not accept it so they are resending it.
