Starbucks fans can now get free refills for some drinks — but not all. The coffee chain is also bringing back its self-serve milk and sweeteners bar.

Starbucks is bringing back free refills and a condiment station, but there are few rules to be able to use these services.

These customers will be able to enjoy free refills on hot brewed or iced coffee, or hot or iced tea during their visit. Starbucks says folks must have their first beverage served in a ceramic mug, glass or personal cup — no disposable vessels — to receive free refills.

No disposable or plastic vessels will be able to get the free refills. Additionally, if you purchase a cold brew, latte, Starbucks Refresher, Iced Tea Lemonade and many other drinks, you won’t be able to get the same drink for your free refill.

Starbucks is offering a 'for here' option for customers to enjoy drinks in stores in reusable mugs, as well as free refills in stores for hot or iced coffee and tea.

Starbucks customers in the U.S. and Canada will notice some changes when they visit a Starbucks location on Monday, including the re-introduction of condiment bars.

The free refills will be served in coffee mugs, glasses, or a clean personal cup brought from home and are only available on the same visit at one store. The refills excludes Cold Brew and Nitro Cold Brew, Iced Tea Lemonade, flavored Iced Tea and Starbucks Refreshers® base. Initial purchase must be made in a reusable cup or “for-here” serveware.
