I've created a userscript that adds a popup message to display referral links and clearance links that are taken directly from Cheapies. It can also show reminders for other things as well, such as using Dosh card to pay for stuff (to earn cashback). I needed this as I have a couple of cards and I sometimes forget that I can use Dosh to pay for my utilities (as normally I have either direct debit or automatic payment configured and so it wouldn't occur to me to use Dosh).
There are also times where I don't see a long standing deal in the Cheapies browser extension, so I can use this script to remind me to check that.
This works on all browsers. Just install a userscript manager such as Tampermonkey or ViolentMonkey. I personally use ViolentMonkey on Vivaldi & Firefox. Then just create a new script and copy and paste my code in there.
Here's the code, feel free to tweak it to your liking, such as adjusting the color of the popup and the location of it, as well as transparency etc.

You can move the popup anywhere on the screen and it should retain its position even after a page refresh.
Wow - a serious bit of work. Ummm how do I get this to work in chrome or edge ?
