This is my plan and actually has not worked out so far as I am not strict on myself.
I have far too much "stock" everywhere. Spent £652 in January for a family of four! Included alcohol, toiletries, everything. Too many bargains -especially expensive meat. February is going to be eating out of freezer and cupboards month with a low spend attitude for fresh stuff.
Loosely Meal plan around the meat in the freezer which is bought on special offer or whoopsies.
Make best use of Aldi Super Six and Lidl weekend offers as they are over the road from each other.
Use mysupermarket.com to order months worth of cheaper food compared to Aldi and Lidl and will always look for deals especially, cheese, shampoo, conditioner, coffee, Wash Tablets, Clothes softener, Toilet Rolls, Kitchen Rolls, Tooth Paste if they are a Savvy buy.
Used to use Costco for toilet paper and washing powder but cheaper in Aldi or Asda.
Will batch cook especially Spag Bol and use the freezer for everything I can't keep fresh any longer.
Use a list for fresh stuff such as bread, milk, veg, fruit, lunch.
I also use as many coupons as I can, and if I can combine them with special offers,
The more you shop the more you are likely to spend due to impulse buys - this is definitely me and have found I spend more on "offers" so trying to stick to my regime of : Aldi Super Six and Lidl weekend offers, Use mysupermarket.com
If there are any other tips to keep costs down do let us all know, thanks.
