It's difficult to say what I've saved not punting as I don't keep a record of what I spend.
As well as saving on not punting, I like a lot of others will have saved on other things such as not having legit massages, meals out, takeaways and visits to the pub.
Saying all that, at a guess I'd say I've saved £300 per month not punting...and taking that from the middle of March when I stopped doing most things I enjoy, I'd say I'm over £1000 better shielding my little trouser-friend. I'd probably double that amount with the savings made on avoiding legit activates too
