End fees on postage and literally every item on Ebay will be sold for $1 plus postage.

 

need a new laptop?.  that'll be $1 plus $3000 postage.

Need a new car? that'll be $1 plus $40,000 postage.

 

It's not going to happen.  It's nonsensical.  the issue here is you need to know your cost structure and price your products accordingly.  User error I'm afraid
