I used to buy Southwest gift cards with Target gift cards, bought on Raise. Even Starbucks cards.
But now the only cards I can buy - Disney gift cards. When I tried to buy Southwest gift cards couple weeks ago, the web-site would let me use Target gift cards to pay for the order, I got a confirmation through an e-mail, but then I got e-mail about my order being cancelled. I tried to do it again - same result.
I called Target, and they told me the policy had changed, you could no longer do it. So I had to use Target debit card, and that still gave me 5% discount. It was not that great as before, but at least something, as you can't really get better then 5% discount on Southwest gift cards anywhere else.
But with Disney gift cards I still was able to use Target gift cards to pay for them.
I suspect Target probably would cut it off some time too. But that is life. If they feel like they are not making money - they would cut it off. They are a business after-all, they'd have to make their profit to stay in business.
