Does this mean if you buy it on week 1, it's free on week 5? Or does it mean if you buy it on week 1, because it's monthly you pay again on week 5?
Hi! It means you pay again on week 5. Theoretically every 4 weeks is a month, so if you buy it on week 1 or 2 then it comes up again the next month (week 5 or 6).
