The key-card trick every reader should know
Antivirus vendors charge full price on their own sites and quietly let Amazon sell the same activation codes for 50-70% less. Buy the key card, disable auto-renewal in the app, and rebuy a fresh card next year at the same discount. Every price below reflects the Amazon key-card street price, not the inflated renewal rate.
