I tried today but they were out of the particular gift cards and refused to put it on a regular Target gift card. We also asked if we could just apply the $200 credit to a new ipad and they said no. So they said we have to come back tomorrow when they get more gift cards in.
They have special cards that are only supposed to be accepted in electronics. Although I had no issue using one to buy several iTunes gift cards at the main registers. Had I not asked they likely wouldn't have known it was different.
