After registration, you will have 21 days to use BLINK without being charged. You can add your credit card at any time during the 21-day trial, however your card will not be charged until Day 22. If you do not add a credit card to your account, your account will be downgraded from Trial to our Free level of service. If you add a credit card for the purchase of a domain name, but do not purchase a subscription plan, you will still be downgraded to a free tier. You will receive a reminder email during your trial period to remind you that your trial is nearing completion.
