Dead Weight

I went to the post office to mail an oblong item that weighed 3 pounds.  It was something that I had sold on eBay for $20.  The postal clerk told me it would cost me $26 to mail it.  Are they fucking kidding?  Being that it's so freakin' lightweight, I asked why.  She said because of its size but lightweight, it's what's known as "dead weight."  I laughed.  The only thing dead weight around there was the post office itself.  No wonder the postal service is going into bankruptcy.  Who the fuck wants to mail something for less than the paid for the actual item itself!?  Especially when it's so freakin' light?!  Give me a break.  I'll either try to repackage it smaller or give the eBay buyer a refund.  What a rip-off.  Bye, bye, USPS!
