Tesco value multi purpose cleansing wipes: these are RUBBISH. They are small, thin, and barely moist. I bought one packet to try, 'cos they were only 36p for 80 but I can safely say that they are only fit for the bin. You'd have to use three times as many of these to do the same job as a single Simple cleaning wipe (they are around £1.00 for 50). Not recommended at all.
Sainsbury's Basics tuna chunks in brine: BRILLIANT! They are 55p a tin which is cheap as chips for tuna. The next price up for Sainsbury's own label range is around 90p a tin. I could see no discernable difference other than the packaging, as I have tried both brands. And the best thing is that they are pole and line caught, which means no marine life getting stuck in the fishing nets.
