The item price can be up to £5000 for GSP to the States. And eBay refunds the Buyer for you in case of loss or damage, generally. Regarding 'safety' it's good to keep in mind that your Items are unpacked and repacked at the Hub, so if you're selling something breakable that you would hate to see damaged/destroyed (even though you were paid for it) because this is a reoccurring issue.
