hey guys, I need your advice please. i just sold a ton of crap on ebay to an international buyer. What type of International shipping should I use that comes with tracking info that I can upload to ebay so the buyer cant say they never received the items. maybe a flat rate envelope? anything that comes with tracking info that is sufficient for ebay in case the buyer claims "i never got the items, i want a refund!" thanks guys for your help with this.. I appreciate it.
