ASA Membership has been down year after year, its the only ongoing volunteer org for access in the dunes.
Here are the publicly available ASA membership figures and updates that have been reported:
January 2020: The president of the ASA shared that the organization had 1,059 active "Supporting Members" paying annual dues. This update was part of a "Push for 10,000" to recruit more dues-paying members. The message also mentioned having 14,890 members in their Facebook group, though these are not official members.
November 2008: An ASA newsletter reported that the organization had over 34,025 members. The Sand Sports Super Show helped boost this total by adding over 1,200 new members.
I don't like paying $10 to use a Credit Card when the common practice is 1.5-3.5%, same as Online handling Fee of $7 and Shipping Fee of $13 is all bullshit.
But it's clear why they do it.
