What a dollar subscription actually costs you
A subscription quoted in dollars is a rand cost that changes every month without anyone sending you an email about it. Over a year that is the difference between a line item you can budget and one you cannot. It applies to every dollar-priced tool, including the ones we are not comparing against here.
It cuts both ways and we should say so: when the rand strengthens, a dollar subscription gets cheaper. The point is not that dollars are worse. It is that you are carrying an exposure you did not choose, on a tool that costs less than a phone contract.
