How it works
Ana joined the Puzzle Box Club. The sign said two coins a month, and a box would come every month until she stopped it.
That is a subscription: it repeats until you stop it, even when you stop using it.
The tiny words said plus one coin for delivery, so each month cost three coins and a year cost thirty-six.
Ana used four boxes, and the other eight cost twenty-four coins for nothing. Read the small print, pick a day to ask, do I still use this, and find out how to stop it before you start.
