ClearAV tries to bribe me

I recently ordered an item on January 13, 2008 from Amazon.com. The shipper was ClearAV.
The Shipping estimate was: January 14, 2008 - January 15, 2008
The Delivery estimate was:January 17, 2008 - January 22, 2008

On January 23, 2008 I wrote the following as feedback on Amazon.com

The estimated delivery date was "January 17, 2008 - January 22, 2008". It's currently the 23rd. According to the tracking info, the item didn't leave the factory until yesterday, the 22nd. I'm growing inpatient, if you want speedy service, go somewhere else. Usually I get packages ahead of time, not with this shipper though, with them I have to wait overtime!

ClearAV then emailed me, offering me a bribe. I was to delete my feedback and they would refund my SHIPPING cost. Obviously I'm not the kind of person that can be bought, plus I don't believe in this kind of under-handed scheme by companies to try to get only positive feedback.

In my opinion, this bribe makes ClearAV an unethical company. They shouldn't be trusted, and I don't think anyone should order anything from them.
