Really not fond of the frozen meat/fish/potato products at Aldi, their versions of fishfingers etc are tasteless and don't cook well, you end up with a small grey stick of fish with a bloated sleeping bag of flabby breadcrumbs hanging off it.
Their nappies aren't great, don't hold much wee. Their soy milk splits in hot drinks, and their coffee is absolute shite (at least the fairtrade one is, can't vouch for all of them)
However, I do shop at Aldi for everything else because it's fab. Obviously the fruit and veg are great prices, I buy their soup mix, casserole packs, leeks, mild onions, etc. they have good offers on meat, I like their skinless boneless chicken thighs, pork shoulder joints, butchers choice sausages, pork mince etc. the cereal is good, they have a good selection of cold meats & dairy, lots of cheap treats and many unexpected things in the bargain aisles!
Also if you buy the daily mirror this Thursday you can get a voucher for £5 off a £40 Aldi spend.
It's take me ages to write this post, so sorry if It's already been mentioned!
