Don't get takeaway (once a month may be)
Clothes - I shop at TK Maxx
Car - Just 1 and I keep it for years. Been driving 8 years now and I am on my 2nd car.
Lego - Stopped buying that, takes up too much room
Guitar/amps - Stopped buying that
Tech - Buy it once and keep it for years. iPhone 6, 2012 iMac, 2010 MBP (just replaced it with a new one).
Food shopping - Mix of Sainsbury's, Waitrose, Co-op, Aldi, and Lidi
But I lately I've moved back into upgrading my camera gear again, it's an endless cycle of refresh I guess but at least tax-deductible, it's pretty much the only tech I keep up. Also been trying to use all my free time for travel, so staying in nicer places, eating nicer things.
Very similar to my lifestyle, except I change cars once a year.
Gambling has got to be the absolute worst way to "spend" money.
