Query: 2x refills are a bargain

I had first picked up the Zebra 701 here locally at a big box office store after reading about how great the pen's are. They write well and are a comfortable weight in the hand, the issue that I ran into was that they only seem to come with blank ink (when you buy the pen). I picked up a refill pack at the store but it was almost $4 just for the blue refill. Thankfully I came over to amazon later that day and found them for more than half off. I saw another reviewer comment that the ink in his refills was poor/dried out, I have not experienced this and it seems to perform just as well as the original black ink that came with my pen. Amazon was priced so well I stocked up, I may not need more refills for years to come. :)
