Norton Internet Security 2015 with backup is that any good!

Greetings fellow Norton users!
I have to ask you for your opinion. My Norton 360 expires in 8 days. For certain reasons I do not have a credit card. Anyway, I want to buy Norton Internet Security 2015 with backup. and then uninstall Norton 360. Is the new program worth of buying? is that as reliable as Norton 360? Please advice me as one of the local store has Norton Internet Security with back up (rebate $30.00 off) only until this Saturday-June 27.) So, please tell me whether it is worth of buying? Because if I open CD, I cannot return to the store. They do not accept opened CD and I will waste $90 for nothing. Please respond so I know what to do. I really do not want to switch to other product. I got used to NORTON!
