Many national chains offered deals on Wednesday in conjunction with National Coffee Day, which is followed by the lesser-celebrated International Coffee Day on Oct. 1. The pandemic has prompted more at-home coffee assumption, so the "holiday" is a chance to lure consumers back. Starbucks is also celebrating its 50th anniversary and is inviting customers to bring in a clean, empty, reusable cup, up to 20 ounces, to participating locations Wednesday to receive a free cup of Pike Place Roast brewed coffee.
