Multisport card from ACA?

Hi guys im paying 250 a month for my gym and about 300 a month for a swimming pool.

I noticed both facilities support a multisport card which apparently this site offers for less than 200 a month

I know multisport is typically an employee incentive, can I get into any trouble for paying this 3rd party org instead, and has anyone used them before?
