When going to webroot site to purchase subscription, I see offer for $ 20 off for 3 device/1 year subscription and $ 30 off for 5 device/1 year subscription. But when I go to, purchase the 5 device subscription it only shows $ 20 off. Not sure which one is correct , before I finalize my purchase.

Calling sales  with the number provided by online help sent to Geeksquad at bestbuy who are of no help.

Suggestions.
