First time post, hope it's good enough.
Found this bug while buying AV for an elderly family member. They originally had 25% off but a popup came up for an extra 10% off if selected within 10 mins, and when you accept it pops up saying the code is for a development environment only. Seems like whoever was testing this out stuffed it up and it's running on their production site instead. Either way the discount works and takes it from 25% off to 35% off on all their home licences (1-3 year subscription).
I've used Sophos in the past because they're well-known in the IT field and their software is hands-off (no ads, no constant popups, just runs quietly in the background). A far cry from your Nortons and your McAfees. Anyway, try if you want.
Steps to obtain:
- Click link
- Go to site and select a subscription length
- Start filling in details then wait for a popup.
- Accept the popup and the page will refresh with 35% off instead of 25%
- Pay, install, start using


I remember using Sophos Home Premium several years ago when they launched it. (They must have had 12 months free or something like that). Very nice cloud dashboard from memory. That said, I don't know how well it rates these days, as there does not seem to be many reviews. Their Business and Enterprise products are different.
