I just listed a spare iPhone 5 with a flat shipping rate of $5 not thinking that a buyer would emerge overseas where they have very little in the way of CDMA carriers (it is a Verizon phone). After looking into shipping the cost to China may be prohibitive at $50-80 or so. I really don’t know how much it costs to ship there. I am afraid it will get lost or not show up or something worse.
Can I just back out without damaging my seller rating?
