Walmart Canada said it’s holding out hope that it can “reach an agreement” with Visa for lower fees.

The two companies have been feuding for years. Walmart sued Visa over swipe fees in New York in 2014, alleging that “Visa’s monopoly power has enabled it to dictate price and inhibit competition.”

Walmart again sued Visa earlier this year, alleging the company is trying to increase profits by using less-secure methods for debit card verification.
