I like that you can pay with cash or credit card, but it's not really convenient to use if your payment method doesn't support EMV chip cards (i'm looking at YOU VISA). The system has been working great since we started using them in early 2018 - no issues! We have used other companies before who would charge us an extra fee when they processed our payments through their service instead of just processing straight from PayPal/Venmo etc., so this was nice because there were NO fees involved after paying via RomExpress' website vs another site charging me $5-$10 per transaction as well!!
