I do my best to get you your cards in the safest, most economical way possible for both of us. Here's how I pack my ebay standard plain white envelope shipping:
Also - I have noticed that every once in a while, ebay will show the item as "delivered" 1-2 days before the item actually arrives. If you get the delivered notification and you haven't seen the item yet, please give it a day or two to arrive. If it still hasn't arrived, I'll be happy to work with you to find out what happened.
Thanks for looking and happy shopping!!
