Large stacks of paper with the pictures of dead guys on them....the ones with 100 in the corner work best....bring lots of those.

Debit or credit cards are not considered cash. The only and the best way for the cahs discount is by electronic check. Hope this helps.

Electronic checks, Money orders. You can mail cash or checks, but wouldn't. Electronic check is the best method for this.
