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

If you've been missing free refills at Starbucks, you're in luck! The chain has announced a return of this perk, but with a few important caveats.

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.
