Ah juice. I didn't think of that. We never have it, but some people have it daily. I can imagine that a daily glass of organic pressed apple juice will be expensive.
Dare I ask how much he was buying at about £3 a litre?
We keep our bulk toiletries, toilet rolls etc under the bed and before we had the kitchen extension, pretty much everything spare went under the bed in plastic crates.
It wasn't a huge volume, just enough to make sure that we always paid the special offer price and never paid full price for anything non perishable that is on offer frequently.
it takes a change of mindset - don't buy what you need this week because you are running out, buy for the storecupboard and then use from there. Only buy when on offer.
Always keep a stock of toilet rolls, shampoo, washing detergent and softner, tinned tomatoes, whatever else you always buy and is often on offer. I don't do it so much now because I shop mainly at Aldi, which just has low prices not ups and downs with special offers, but you could do this and still shop in Ocado and still save.
Instead of buying the same things each week, look at what is on offer and buy those. I know in Waitrose, the Charlie Bighams are sometimes on offer, so maybe they are on Ocado too? A lot of them can be frozen, so maybe buy a few when on offer?
Another way to save if you are shopping online, is to rotate as many differnet shops as possible. If you miss a few weeks with one particular shop, they will send you vouchers to shop with them again.
Waitrose also have the MyWaitrose offers, where you can choose your own offer from a selection, to get 20% off. I find this fiddly though, but don't regularly with Waitrose.
Have you also checked your utilities and other bills to make sure you are on the cheapest tarriff if you are looking to save money. Do you use Quidco to get cashback when shopping online? Do you always shop around when renewing insurance etc? Do you look for online offers and discounts when visiting attractions or eating at chain restaurants?
