Payment in the form of cash, check or credit card is accepted. Non-member payment is required upon receipt of Mad Money.

Mad Money gift card funds do not expire. Unless prohibited by law, a $3.00 fee will be deducted monthly from the card balance, starting the 1st day after 1 year of inactivity. Activity means any action resulting in a change of card balance - other than fee imposition or adjustment due to error or a prior transaction reversal.

Businesses process Mad Money just as they would a normal credit card.

The Mad Money program runs on a closed-loop system - which means that participating merchants must be active members of the Chamber to accept the card.

There are no software or equipment changes necessary to current POS systems. However, if your business updates its POS system we will need to re-enroll you into the program.
