If you shop at Target a lot, it's really a great deal. Of course that's only if you pay off the Redcard every month and not accrue any of their usury-level interest.
I'm really hoping I can link my Redcard to Apple Pay (though it said no store cards at inception), and use that at Target. I keep my Redcard in the third fold of my wallet, and using my phone would really be much easier.
But do you get 5% off every purchase or just the first? I'd thought it was only the first. But, either way, I get better rewards from my other cards.
