I just bought my TF-100 kit about a month ago. I see there is a Black Friday deal on the refill kit. I know what I have enough to last until next Black Friday. Is there any reason why I shouldn't go ahead and get the refill kit?

The TF-100 test kit should last you a full year if not into the 2nd year unless you have a major water chemistry problem that requires very frequent testing.
