# Why does the coupon box say a code would bring the price under the minimum payment?

Because after any discount, every payment is either **free** or **at least one US dollar** — never a few cents. A code that would take the price of every plan it covers somewhere in between can't be used, so the coupon box tells you straight away rather than at checkout.

Why the rule: payments of a few cents can't actually be charged, so they get carried forward and turn up later as a confusing balance on your next invoice. Keeping every payment either free or at least a dollar avoids that.

If a code only takes some plans under the minimum, it still works for the others; for those few plans checkout simply shows the full price. If you think a code you were given should work, email support@storagestudio.us with the code and where you got it.
