Need Help Finding Reinkers

My wife has several "Stamp'n Up" ink pads that are needing reinked. We have
looked locally and on the internet for reinkers but can't seem to find a
source other than a demonstrator. Does anybody know of another source for
reinkers? It doesn't need to be "Stamp'n Up" if we can match the colors.
She also has "Color Box" and "VersaMark"

Thanks
