“if you get a drink at the beginning of you Target run you can get a refill before you leave,” the video’s on-screen text reads.

“Another excuse to go to target,” Ariza captioned the video.

However, there are a few stipulations.

In order to get the free refills, you must have the Starbucks app and be part of the coffee chain’s rewards program.

The offer also extends only to teas and coffees.

This eliminates many of the fan-favorite drinks Starbucks fans know and love.

But it may also work even if there’s been a staff shift at Starbucks.

Regardless, the hack has been called “life changing” by some TikTokers who were unaware of the policy.

Some had never even heard of the policy.

“I work at target but I’ve never heard this what,” someone wrote.

Others seemed to believe that the hack worked outside of Target Starbucks stores.

But not everyone was supportive of Andrea’s hack.

“Even if this it true- I feel like im going to get embarrassed,” one TikToker wrote.

“As a target employee. Nobody finishes their drinks. They just leave them sitting on shelves,” someone wrote.

“Some targets will charge $1.15 for a refill. That’s what the one I used to work at had is do,” another person said.

“If I get a drink at the beginning of my target run.. I’ll be [running] to the bathroom mid way through target,” someone else said.
