Hookah Websites & Anonymous Checkout

Hi all!

Was wondering if anyone knows any Hookah sites that allow for anonymous checkout or if anyone has any information about age verification on websites that sell hookah tobacco in the United States and/or more specifically California.

Can hookah websites have annoymous checkout, where age wasn't verified or are accounts required?

Does a checkbox, suggesting that you've read over terms and conditions which include a line stating that you must be over 18, count?

Thanks in advance all!
