Uhoh..
First post and it's about "selling stuff" plus you have a nick that closely resembles one of our trusted and well respected members.
That is NOT a good start!
Anyways, to answer your question:
try uship dot com
I see that website popping up every now and then when I'm searching for specific kart pics... and it appears to be a good choice in most occasions to ask for shipping quotes,
since a kart is way too big to just put a stamp on it and call it a day
Another advice:
Do not post your ebay links here.
Not until you filled out your profile (proper location, real name (at least real first name) etc.)
Your username can be considered lure, and we want to make sure it's just a coincidence, right
