I sell stuff on eBay a few times a year when I have a group of stuff to sell. But the sellers I hate the most are the sellers that inflate the shipping. I saw a computer case a few months ago selling for 10.00 and but it was 110.00 to ship. Once I get the zip code of the seller I check out rates and message the seller with a price I am willing to pay to ship. Either I never hear back (99% of the time) or the seller comes back with "I need X more for packaging." Usually it's $30 or $40. I usually never reply back except to notify eBay of the seller but nothing ever comes of it.
