Cannot stand Heinz tomato sauce since living overseas. Now has to be All Gold Tomato Sauce (South African - tastes like real tomatoes and not so acidic as Heinz). I get from Ocado or amazon!
Has to be twinings tea. And DH buys coffee beans from a proper coffee wholesalers.
Mayonnaise - M&S own brand but co-op will do when we run out.
Cordial / squash - I'm trying to avoid sweeteners and I love the belvoir elderflower & rose cordial but it's expensive so I buy in special offer only.
Instead of sweetener laden squash we have switched to watered down apple juice. Co op Apple juice!
Has to be Colman's mustard, Branston pickle, Cadbury's choc buttons, Ella's smoothie pouches (kids won't touch the Lidl equivalent!).
Im on a gluten free diet & DC dairy free so that brings its own problem re cost so I buy GF pasta, bread and oatcakes when they are on special offer. I've also found Morrison's do the DF yoghurt pouches but no cheaper than Ocado so I buy them as a treat every couple of weeks.
Unfortunately most of the supermarkets, in particular, Lidl and Aldi, do not have a big enough audience so no point relying on them for GF or DF. My local co op is pretty good for GF though.
I find GF cereals super expensive so try to buy on offer and limit how often they are eaten!
We buy organic milk, real butter, organic free range eggs veg, fruit and meat from riverford every 3 weeks. Lasts well and we buy well but don't overeat. We also use up leftovers to reduce wastage.
Co-op is a good shop to stock up mid week if we run out but we rarely do.
My kids are used to things running out and not being replenished immediately. Too young to understand it's due to cost!.
