I was literally saving some (generic American Express) gift cards for a B2G1 sale to pick up some 3DS/Vita games. And, of course, I will be away for nearly the entire time the sale is happening. I do fly back next Saturday (3/23), so I will make a last minute run to Target. Hopefully there's some scraps left for me.
From what I've seen, this sale is usually online, too, but everything [decent] goes OOS immediately. If you're up late you might be able to snag what you want ...maybe.
