Agreed, Jane.
Donate any amount possible. And not to hijack your post but on the bottom of the fine print of that donate-page, one can also donate via tradition check instead of credit card.
In fact there are two sources the check can go to:
Trump Make America Great Again Committee
310 First St SE
Washington, D.C. 20003
OR:
Donald J. Trump for President, Inc.
725 Fifth Avenue
New York, NY 10022
Thanks. Many prefer to mail a check.
