was going to send from Pennsylvania but i see you already have 2 at least. May i suggest to OP, a list up front of which states are covered. Good Luck :0)
How about Florida, New Jersey and New York? Do you need a note written on them or just the postcards? Always glad to do something for a child or someone who helps a child.
Also do they need to be postmarked in those states or are just he postcards themselves enough?
