Usually if you can’t renew online it is for one of the following reasons:

1. You owe more than $1.99 on your account. Keep in mind that this can occur mid-renewal. If you have 3 DVDs that are 1 day late you would be able to renew two of them, but after that you would owe $2.00 and would not be able to renew anything else.
2. Someone in your family to whom you are linked (child/parent) owes more than $1.99.
3. The item you want to renew is on hold for another patron.
4. The item has already been renewed once.
