Buy Now Ticket Purchase

I’m setting this up for our local Chamber of Commerce, and am understanding the membership level options (using Pro version for Authorize.net capabilities)

The Chamber also wants to sell raffle tickets to anyone who visits the site at $100 per ticket, with the option of buying multiple tickets. This would not be contingent on any membership level, and we do not want to require them to register as a member to do so.

How can I set up a simple Buy Now button, let the person select how many tickets, and pay for that many tickets as a standalone transaction through Authorize.net?

Since s2M is not set up as a shopping cart, I am not aware of any way to select more than one item to purchase at the time.

Since those purchases would not be contingent upon a level or a custom capability, did you consider a cart plugin just for those? I cannot recommend any as I never used one but maybe that would be where to look?
