Plastiq is an online bill payment service that lets you pay almost all of your bills by credit card. Plastiq’s standard fee for credit card payments is 2.5%, but for quite a while they’ve offered a promotional 2% rate for MasterCard payments. At some point not too long ago, that promotional rate ended. Now Plastiq charges 2.5% for all credit card payments including Amex, MasterCard, Visa, and Discover.
