Topic: How to package your cards
The worst trade you can make is one where you unintentionally destroy your cards. Please follow these guidelines written by an experienced trader in our community to properly pack your cards and ship your package for $1 less than what the post office will charge you. If you're looking to trade regularly, I would suggest buying size 000 bubble mailers in bulk from ebay for less than 50 cents apiece.
