Many ISPs, including giants like Time Warner, will give you $20 of credit on your bill for referring each friend to their service. Of course, there is a catch. You must consider that when refering a frined, you want to make sure that you are satisified with your service. Also, when you are referring a friend, you are giving out a friend’s information to be contacted within 24-48 hours. Unless your friend signs up for service and maintains that service for 60 days, then you don’t receive the credit. Also, you won’t receive the credit for 90-120 days, so you must maintain your service to get the credit. When using Refer-A-Friend specials, make sure that your friend will not only be happy about being contacted, but will also sign up for service.
