My "go-to" Target that I always drive out of the way for because of the super nice cashiers that never give me attitude about coupons, cartwheels etc refused my gift card for Disney gift card purchase yesterday, too. They said it was new policy and they felt horrible, but were not allowed to do it anymore
I have purchased this way at this location for the past two years and even had this manager "praise" me on my savings, so I absolutely don't think it was a situation of them just not wanting to do it. But still, I was hoping that they were wrong...
