It's a great app. The only issue is that they change 1.99% if you use a credit card so you dont save much other then a few cents. The only way to wave the fee is to use a bank account.

Hi Jonathan, thanks for sharing your experience—we're glad you're enjoying the app! As you mentioned, Mudflap is free to use with a debit card or bank account, so you can avoid that 1.9% credit card processing fee by switching your payment method. Mudflap prices and discounts vary depending on retail and the cost each of our stops sets. Fuel prices fluctuate daily, but we aim to deliver the best discounts available to you. If you have any questions or need help switching your payment method, our support team is happy to assist at 1-888-885-3835 or [email protected].

I was very skeptical at first on how it worked and my area was very limited when I joined in the summer of 2024. In the last 12 months mudflap has expanded and almost has every diesel kwikstar in my area. Super easy to use and the discounts range from 20 cents to 75cents off a gallon. Overall I am extremely happy with mudflap. Ps not having to use a credit card or debit card at the pump is awesome when it's freezing cold out. Punch in the code and there's no wait time even. Just grab the nozzle and pump. Fuel stops in 60 seconds or less in my cummins.
