I
have many different packs of cards you can combine any single pack
listings I have and get a flat 5.00 dollars shipping plus 30 cents per
extra pack.
As an example 20 packs would cost 5.00 dollars for first pack and 5.70 for the next 19 packs 30 cents each for a total of 10.70.
This offer is only good for U.S. buyers international buyers will pay what shipping cost to your country what ever that may be.
