EDIT: I probably should've said up-front that I live in the UK.

I've started to really dig shaving over the years. It's gone from a chore to an enjoyable regimen. Watching or just listening to shaving ASMR videos provides considerable satisfaction, though it's really always nice to see a professional at work. I only shave every few days, once my stubble has become quite unsightly, and just give it a single pass in order to save on the cost of razor cartridges. At the moment I'm going through my remaining Cornerstone cartridges after canceling my subscription with them due to the cost, and I can get a few uses out of each before having to discard them. My shaving gel is just a cheapo brand, and the aftershave is an old Christmas gift.

I'd like to be be able to save some more money when it comes to shaving. Anyone got any recommendations for a good brand I could switch to, or advice on keeping the handle clean and getting more uses out of the heads?
