Can I set my own monthly budget for the bandwidth?

Yes, you can. To set a monthly bandwidth budget, log in to your account, go to Webfonts, and click on Stats. After the monthly limit is reached, the next font specified in the font stack will be used until the end of the month. From the 1st of the next month, the first font will be used again until you reach the limit, or raise the budget limit. You will receive an email notification when the limit is reached.
