Not exactly wrong. They do take low variable $0.10-0.25 flat fee, then another 0-3% from the purchase depending on the card and merchant. They don't take 25% though, that's misleading. If the purchase is $100, they take around $2 in fees. If the purchase is very low, they'll take 25%. Hence why a lot of stores say they won't take Visa or Mastercard on low value sales. The seller also has a choice of not taking credit card and not lose 50% of their potential sales.
