How to get free McDonald’s fries every Friday for the rest of the year

McDonald’s is giving away free fries.
The deal kicks off this Friday and runs every Friday through the end of the year.
In order to cash in on the deal, you have to use contactless mobile ordering and spend at least $1. Customers must also pay on the app.
McDonald’s says customers also have to opt into the McDonald’s Rewards Program to qualify for the free medium fries.
