I asked at my
Disney Store here in STL and I was told that the pre paid gc's from Target were a separate thing from what they sold in store. Therefore, I was told that I could not bring those in and load them all onto one card (or a few instead of 20). It should all be the same thing, but I am only going on what I was told
I now have 2 gc's that have money one them, that way if I do lose one it's not a huge deal. I plan to take pics of both our cards on my phone, front and back, so I have proof of them, just in case.
