I just started at target about 3 weeks ago. After looking through my new hire packet I came across papers about the credit union. I signed up online. When asking my coworkers if the extra 5% works when using the credit union card everyone was clueless. Only 1 person I spoke to knew about the credit union but did not know if you got 5% off when using it like you do with a red card . So my question is , do I have to link my tcu card with the target red card to get the 5% ?
