# Show several rates

You can add a validity date to your rates, for example if you want to offer a discounted "early bird" rate well before the scheduled date.
You can also set a quota if required.
* It is sometimes useful to offer a preferential and confidential rate that will not be visible on the site. In this case, uncheck the box **"publicly visible" **and send your invitation to one or more participants.
