A cup of Starbucks coffee charges around $1.50 to $4, depending on its size and flavour but is now testing to offer small cups of coffee for $1 with free refills in Seattle-area stores.

The 8-oz small size coffee is not on Starbucks’ menu but is available on trial basis.

Starbucks spokeswoman Bridget Baker said in a statement that the test “is not indicative of any new business strategy.”

“Testing is a way of life for us, as we are constantly looking for new ways to connect with the customer and provide the best Starbucks experience,” she added.

However, Starbucks do not reveal much information like when the test began, how many stores involved and whether other brews also going for the similar promotion.
