when i go back to change the price it wants to charge me again! how can I change the price without getting charge again, or maybe I can change it ones its posted?
You can't change the price without being charged for a higher level package when you increase the price on the vehicle. Listing a car on eBay Motors is not the same as listing clothing items etc. you are charged a fee up front for the listing.
Listing package fees apply to each listing you create, are charged at the time of listing or relisting (if you opt to auto-relist), as applicable, and are nonrefundable. Fee amounts are based on the terms in effect when the listing goes live
