Starbucks is inviting customers to bring a friend and rekindle the spirit of the season with a buy one, get one free offer on holiday beverages. Catch up with a friend over a holiday beverage. When you buy one, we’ll give you a second one of equal or lesser value for free at participating stores. Both Saturday and Sunday from 2 to 5 p.m., customers can choose a hot, iced or blended version of the peppermint mocha, gingerbread latte, eggnog latte, caramel brulee latte or skinny peppermint mocha and get one to share with a friend for free. The offer is good at participating Starbucks company-operated stores while supplies last.
