The redemption value of each PTC Point equals One U.S. Dollar ($1.00). 

Meaning, that if you’d like to purchase something that costs $20 and use only PTC Points, you would need to redeem 20 PTC Points through the app. Alternatively, if you only had 5 PTC Points, you could redeem those points (equal to $5) and pay for the balance of the item ($15 in this instance) with other forms of payment that the business accepts.
