Updated 10/16/24 - Coming back to the game a bit. I love to trade so please trade with me!

SHIPPING
Like everyone else, I put my cards in a sleeve, then put the sleeve in a toploader. Generally speaking, if a trade is less than $20-ish dollars I will use a regular envelope without tracking; greater than that I will use a bubble mailer and tracking.

For tracking, this is the best method of shipping I've found so far:

CARD QUALITY
I will always check my cards to make sure they match the quality listed on my TL. If there is a discrepancy, I will absolutely let you know.
