We had a Target CC from the U.S. and used it to purchase Disney GC's. That was several years ago. I ran into an issue where I was getting mail from them stating they were going to revoke my Target CC because they felt the purchases I was making was for resale, which was laughable. I bought a few odd items never totalling more than $20 but purchased Disney GC $500 at a time. I made payments in that amount at the same time so there would never be an outstanding balance that I would have to mail a cheque or money order for. I did that 5 times (I think it was). I called their head office and spoke with them about it, explaining what I was purchasing and that it was to pay for a trip, and they stuck by the threat to take the card. If I can't use the card for GC purchases than I certainly didn't need it so I told them to cancel it right then. I don't need someone ruining my credit by revoking the card.
Telling you that story to let you know my experience. I have read about others who didn't have that problem but they were U.S. citizens so maybe that was the difference. You can get a US Target card but be aware, they may have issues with your purchases.
