My nearest Aldi is a bit too far away to use regularly, but we do have a Lidl that we use at least once a week.
I love it, products such as their W5 washing up liquid, far better than Fairy and much cheaper. They also have named brands on offer, recently it was a large jar of Nescafe instant coffee that was over a £1 cheaper than Morrisons, who were actually proclaiming it as a "special" offer.
I have also bought fresh meat from Lidl, their rump steak is consistently good. chicken thighs ( lots more meat on them than drumsticks) at around £2.25 a kilo, and they do "proper" parmesan cheese at a very good price!
PS The brand of coconut milk they sell "Vitasia", is so much better than others that I've tried!
Envious there was a thread that was sort of about this, i.e. asking for recommendations for own brand products not so long ago, it ended up being a pretty long list, with quite a few Aldi products in there, might be worth tracking it down?
(I would but I'm desperate for a wee, and no doubt by the time I come back someone will have found it!)
