I had the free loaf of bread offer but when I went to the store I couldn't get the offers to load in the app (to see which loaf it was) - so gave up!
I do most of my shopping in Tesco, though, and get a lot of points. I always treble the value at reward partners so recently they've been used for Eurotunnel; a six place setting from Denby; jewellery from Goldsmiths for a special birthday gift and I'm having lunch with a friend on Monday so exchanged £13.50 to pay for two courses for two at Chef and Brewer!
In case it helps anyone, Tesco are currently offering a free trial of their Clubcard Plus subscription. It normally costs £7.99 a month but gives you 10% off two big shops a month (up to £200) plus 10% off their non-food brands (F&F, Go Cook, Fox & Ivy, Carousel) at any time.
I pay for the subscription and usually stock up with meat, wine, coffee, store cupboard, household and toiletries on the big weeks and just top up milk, fruit and veg between times. After paying the monthly charge I usually save £32 a month on my shopping!
