Covering everything, food for 3 (including a hungry teen with very fussy tastes and training for competitive sport), cleaning products, alcohol for 2, delivery charges on those items we need to buy online, etc.
I currently budget €1200 per month (so €300 per week) - that increased from €750 to €800 in early 2019, up to €1000 at the start of 2020, and to €1200 in April 2020. Due to a combination of factors.
Prices going up in general.
DD tastes changing so needing more things like turkey, protein bars, health food shop items rather than supermarket items
Our work only getting more busy so needing more convenience
Brexit changing supply options, brands coming off the shelves etc
Covid only multiplying that effect, and various gaps in supply chains causing prices to spike
Covid also caused changes in our eating habits as we are now all home all day - more coffee, different lunches, more snacks, but spending less time cooking proper dinners (that latter is more pressure from work caused by Covid than directly because we are home more due to covid)
WFH means I cannot get to some shops I would go to relatively frequently near my office in the city - Asian supermarket, Nespresso, Italian deli, large M&S (which was great for yellow stickers) etc.
I am also not able to get to the off licence I used to go to relatively frequently as that is outside my 5km limit - the ones nearer are more expensive. Nor a number of things we'd get when visiting Ikea, or from the Farmers' Market on Saturdays when "down home" to visit our extended families.....(the latter means I have discovered a few of those stall holders have an online presence, but needed to order larger amounts to reach the min order limit and also had delivery charges on top....but after over a year without things like the hot choc that we love, I was willing to pay it recently etc).
I generally grow a fair amount of our veg in the summer but that was not as good last year for lots of reasons (I was too busy, GC was closed for baby plants at the wrong time, GC was sold out of baby plants and seeds when it reopened and I was a day late, and weather and constant football thumps killed off a lot of what I did get going). So that also dented what should have been some savings in the summer.
We are conciously supporting local businesses also, so bread, fish, deli items and meat are costing us more - but we are able to and happy to pay that.
I do use coupons and loyalty programmes - but they are not as available at the moment as in normal times.
And my freezer is still struggling to adapt - I have lots of small tubs of leftovers from when only 1 person would be home for dinner and it would suit fine - but now DD won't eat those, they are too small for DH and I am getting so little time to cook that I can't organise 3 different meals.
If I needed to, I could spend a LOT less.
