Here at Tropic Waters we want to reward you for continually choosing us. So, we have what we call the True Blue Club which is an in-house 5% rebate program. We keep cards on file and record 6 purchases and on the next visit we add up all 6 purchases and give you 5% back on your pre-tax total to use whenever you want and on whatever you want. The card stays in the store, we take care of everything.
