Stopped shopping through Ocado, and shop at Lidl instead, though keeping our veg and meat organic, and so, to afford it, I have reduced household meat consumption by about 70%
Given up Sky - we don't watch tv - and all movie/books/music subscriptions
Cut out all minor insurance plans on specific items
Stopped most donations
I go out about once a month, and have drastically reduced my coffee-to-go/snack consumption
I only buy essential clothes, i.e. school uniform, activity-based clothing, underwear, etc.
I do my own hair and my son's is cut by my ex-DH
Absolutely no impulse buys at the shops, and no internet shopping for things that aren't requirements
No international phone-calls through anything other than Skype-to-phone
I've switched my gym membership to a yoga studio (£30 cheaper)
