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

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.

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.
