I spend about £68 normally on my food shopping, it always seems to come to the same price, i roughly buy the same every week though.
This however doesn't include of baby milk, nappies and wipes, and lucozade for my son (who is diabetic)
I have a partner and a 7 year old and a baby, i normally buy a couple of packets of mince, a packet of chicken breasts and a packet of low syn sausages, and i have things like fish fingers and waffles in freezer for them for emergencies, then it is just things like veg, potatoes, pastas eggs etc. All my food lasts me the whole week. I normally buy the supermarket own brands, there is the odd thing that i buy brand name though. However i grudge spending over 1.50 for a bottle of diet coke so i normally buy supermarkets own and can get 3 for less than the price of the brand names. Another thing is weetabix, i used to only buy the proper weetabix but tesco have started selling a new brand called country barn, i thought it would be disgusting as my partner bought it, however it is absolutley fine and only about 98p for 24, well cheaper than weetabix. Don't get me wrong i still indulge sometimes but all the things i buy and nice and the family all eat them.
I have a relative that only buys everything brand name , and she is constantly saying how skint she is, however they won't budge or change anything on their shopping.
Ha sorry for rambling on and giving you the majority of my shopping list, it will just give you an idea.
