We talked about the sales season last week. This can be a chance to buy and try out something 'extra' to your security software for a reasonable price as well.
You can look for offers on computer 'cleaners' for example which help remove redundant files and cookies that can be exploited by hackers, a best-in-class browser guard or a subscription to a password manager.
Always research what are the best-in-class products at the moment you buy as this can change rapidly (and is why we haven't recommended specific brands).
