If it’s just food and basic household products it can be done.
would buying washing liquid be cheaper than capsules, added benefit of better for the environment.
Also if it’s just 2 of you can you not just do a bowl of washing up each night and save on dish washer tablets and running costs. We are a family of 5 and don’t have a dish washer or dryer for that exact reason.
It depends what your like with food, for us food gets wasted if we buy ahead for a full week. My DH is completely fresh food blind, cooking or using anything fresh no matter how many times I kick off just dosnt happen and when he packs the shopping away he will just chuck any fresh groceries on top of old fresh groceries resulting in me finding rotted food piling up in the fridge and constantly throwing food out. Today alone I fed the dog a whole packet of ham, 3/4 a packet of grated cheese, a full packet of corn beef and a massive sirloin steak for dinner. I didn’t even know the steak and beef were in the fridge as DH bought them without telling me. I also threw out several bags of lettuce. We are very different but DH dose the bulk of the cooking so it’s an ongoing issue. I’ve found buying as we go for fresh food reduces waste but increases cost as I buy smaller packs rather than in bulk. He’s away this week so I did a full weeks shop with fresh food I know won’t be wasted as I will have to do all the meals.
Anyway, shop at Aldi, Tesco’s is good for Aldi price match. Buy what you know you will eat that week. If you are a person who dosnt know what they feel like then try keeping certain things in so you only need to pick up fresh ingredients to add to them, such as if you have a favourite jar sauce or meal that you have the relevant herbs and seasoning in. Today I bought chicken thighs, no idea what I will make but I have DDs favourite chicken tonight in the cupboard, some curry pots, a pad Thai mix, plenty of tinned tomatoes herbs, pasta and rice in so I will come up with something on the day.
Shampoo and household goods I tend to do a quarterly bulk buy at home bargains and stock up on household basics & toiletries. Also at 2yo I never used shampoo on my DDs hairs, only ever plain water for baths and hair washing. They have 3 different types of hair and none of them needed shampoo at that age.
