4% Extra isn't as good as when Raise offers 5% more, but so much depends on the prevailing %-off that the GCs are selling for and IF the GC is included in the sale.
With the cardcash Target GCs selling for 6.3%-off, the net savings is about 10.1% off of the face value of those cards. It's probably the best that I've seen since Christmas. You might find a better deal every once in a long while but this one is pretty darn good.
