I do only buy blueberries etc when on special.
I often go to 2 supermarkets just so i can get cheap fruit (usually lidl or aldi or coop when they have specials) and then to tesco to get bulk of shopping.
I find things like yog cheaper at tesco as i buy cheapest tesco range (like their 6 little fromage frias no crap in them and only 48 pence) I never buy what i'd LIKE all the time altho tempted to do it one week to see how much more it'd be.
I buy the cheapest of the range with minimum requirements iykwim, like squash, i'll buy the cheapest one but has to have no crap like sweetners etc in it. Usually can get a bottle for around a pound.
I don't buy chicken breasts unless they are on special, Coop often do 2 packs for 7 quid and that will do twice, There is no way i could make 2 breasts do us two meals without dp making a comment like 'does this have chicken in it??' And i do bulk it out already with extra cheap veg.
I buy thighs usually and i buy mince. Only buy other meat if they have some 'nice' stuff on offer.
I never buy cakes biscuits etc except the odd pack of rich tea or digestive.
I make meals from scratch with basic ingred and bulk out with pulses and veg too. Typical week would be
Breakfast always cereal (do have a choice of about 4 cereals but only cheap ones and on special ones) and toast (buy loaves 3 for 3quid)
Lunch usually sandwich or toast and beans or baked pot.
Dinners
Homemade meatballs and spag
Veg mousaka (loads of beans and chickpeas)
Chicken stir fry with veg and noodles (usually a red pepper and mange tout)
Mince and tatties (big thing of mine to do spag bol too)
Pizza (homemade) and salad
Chiken thighs roasted with veg and cous cous
Soup and crusty bread (usually followed by baked rice pudding)
For pudding if any, we usually have fruit and yog or i make rice pudding or crumble using rhubarb from garden, have custard made using powder rather than expensive cans etc
I buy eggs locally and altho we are very rural cheapest ones are around 2.30 for a dozen at £1.
I really don't buy anything too fancy, except actually 'lady grey' tea bags but even they have been on special offer lately and i alternate them with cheap earl grey from lidl.
I do also have nights where we'll just have left overs or toast and beans or egg on toast but its usually when its just me and the kids and dp away working.
i also have 2 large dogs to feed which costs around 10 quid per week too.
I find life is so busy i don't always have time to firstly think out what we need so as not to over buy and also time to do things like de bone the chicken thighs etc
No take away near so very rare treat no more than once a month.
I'll be watching my spending and will meal plan etc. I will find a way.....
