Cold Foam Days at Starbucks take place from May 7 through May 11. Rewards members in the U.S. or Canada can add cold foam to a cold beverage for free. Starbucks has a legion of dedicated fans out there who probably love and hate their relationship with the store in equal measure.

Starbucks cold foam or its delicious sweet cream -- which should you choose? Well, it depends on what you're looking for as the two are quite different.

As a sweet coffee-loving gal, I know how tempting adding cold foam to your drink can be. That extra price, though? Not so tempting. That’s why I’m absolutely elated to report that Starbucks is offering free cold foam customizations to iced beverages for the next five days.
