i used to spend £100 on husband and i , and now with formula i did £90 for two week shop
my principles that i follow are
* Why pay for lunch for me when i can eat the left overs from last nights dinner instead of having seconds
* Order online less temptation, and my supermarket always make errors which i moan about so often get freebies, ie i complained about them not having apples and i got my delivery saver price of £60 refunded!
* Try and have a reserve pot for offers, Dishwasher tablets washing powders etc so that you can stock up when they are on offer
* Buy Meat when its on offer yesterday i bought a freezer pack from the butchers, sausages, chicken, diced steak and mince, i then sat and worked out two weeks of meals from them. it means you waste less as i shall cook some meals and freeze them today, so im using all my mushrooms and onions etc instead of throwing the odd ones away
* biscuits crisps snacks are chosen based on their offers.
* and move down a brand, if you bought finest try tescos own, if you bought tescos own try value, and if you dont like it dont buy it again, i wouldnt buy value meat but there are several things that i now buy in the value range and no ones noticed, and i used to be a food snob.
* meal plan, each week i draw up my menu and write it on a chalk board, (looks like a bistro pub so its exciting) so i only buy what i need, and eat in order of perishability of the food. (i used to start each week throwing out a fridge of food now it dont)
* if you have larger things like chicken breasts, i trim them down to a smaller size then cube up the edge piece and freeze do it again the next week and ive had a free meal out of something i would have eaten.
hope this helps probably nothing new, but its brought down my meal costs.
