You can get get theatre tickets cheap for most shows online or by queuing in the day. MSe has links.
Toilet roll is very cheap. Deluxe from aldi and Farmfoods 18 roll packs in deluxe and standard are both better than Andrex.
I buy both Farmfoods and Aldi regularly but stocked up on half price Andrex at Xmas but I'm shocked at how poor it now is, soft but too thin. The others are soft, strong and cheap.
Cars that are 1 2 or 3 years old are s bargain. Some brands come with 5 or 7 year warranties so I don't think car's are necessarily expensive. It's a choice to spend more over a certain point.
Lots of 2 for 1 on dining out. Also railcards give cheaper trains but also cheaper meals out.
Meerkat gives 2 for 1 cinema and meals.
Dominoes is expensive with rubbish deals. I only get it if passing and s lunch time deal I'd available do mini pizza and can for £3. I've never had it otherwise.
