Shipping is $1 (In the US only) in a top loader and standard envelope - I can combine shipping on 2 cards. If you buy 5 or more the cards will be mailed in a padded envelope for $4.50 - anything you buy the same day over 5 cards will never go over $4.50 shipping.
If Buy it now auctions do not combine shipping - I will refund the discount after you pay.
