At least you know where there are savings to be made, if you wanted to!
Yeah, lots of reasons:
Ate out a few times on holiday - which is abnormal for us
Had our big meat shop at Costco buying in bulk, which will last for some time
Had to refill loads of booze - we still need gluten free beer though
I'm on a diet and my food costs quite a bit
Due to said diet, my husband has been doing the weekly shop, selecting convenience foods, freezing them, not defrosting them, and having to rebuy to have something that night
So yeah, we can definitely cut the bill down. But we still average £825/month.
