Happy National Coffee Day! Here's where you can get deals and free coffee in metro Phoenix

Tuesday is National Coffee Day, the ultimate day to get — and stay — caffeinated for little or no cost.

Restaurants, convenience stores and brands alike are toasting the made-up holiday, which is held annually on Sept. 29, by giving away free coffee and serving up discounted brew.

The free cups might also help you stay alert during the first presidential debate between President Donald Trump and former Vice President Joe Biden. The 90-minute debate starts at 9 p.m. EDT.

Starbucks is starting the holiday early for members of its updated Starbucks Rewards loyalty program that launched Sept. 15.

On Monday, the Seattle-based coffee giant kicked off its monthlong "Starland" augmented reality game with more than 2.5 million prizes like free coffee, free breakfast and stars.

Then on Tuesday, members who order a grande or larger handcrafted beverage using the order ahead and pay feature on the Starbucks app will get a free drink loaded to their account for use on their next visit.
