Shipping is 75 cents for the first card, 25 cents for each additional card.  Orders of 9 cards or less are shipped in a plain white envelope (PWE) -- Cards will still be secured inside hard top loaders!  Orders of 10 cards or more are shipped in a bubble envelope with tracking.  Orders of $20 or more are also upgraded to a bubble envelope.  So, if you order 10+ cards or your total is $20+ then your order will ship in a bubble envelope.  All cards are shipped in top loaders no matter what!
