Welcome to Listia, please don't let people intimidate you, they probably forgot that they started as you, not knowing everything and they learned as the time went on. FYI there are some rules on Listia, we are supposed to follow, inc. shipping charges. If you're posting a high amt. of shipping, you'll have to specify what kind of shipping, does this include sign confirmation, etc....You can check it here https://www.listia.com/rules The link is at the bottom of the page. Good luck with your listing.
Very good advice about the link above. I just wanted to add for the future if this was listed as free shipping you would get BIG credits for this one. When you charge shipping on items you may only get about 1/4th of what you would have. But, that being said....if you have to charge you have to charge.
