The promotion will run all day (while supplies last) on Saturday at participating locations. Most locations are open on Saturday from 5:30am to 4:00pm, but you probably want to call ahead and check before you make the trip.
If you can't make it on Saturday, the chain has a limited-time printable coupon available online for the same thing. You can print it out from here while it's still available.
