I have 400 orders on Amazon this year (I think that means I have more than 400 unique items since one order can be more than one items, but it's probably around 450 items total so not far off).
Of those, I probably have a good portion which is household goods as I mentioned, like soap in bulk, soda cans in bulk, etc. which is cheaper than any other option (especially because I don't have a car in London).
Then I have around 170 orders which are items I got for free through the Vine program (https://www.amazon.co.uk/vine/about). And probably around 30 orders that are free books (https://www.amazon.co.uk/firstreads).
If I ignore all of those, and take only recent orders that I paid for, here are 5 items that I can't buy, or at least wouldn't know where to even begin looking for, in central London:
- A luggage and suitcase scale
- A monitor arm
- A good shower filter for hard water (not the crap that doesn't actually filter anything which you can easily find anywhere)
- A label printer
- A moth repellent for wardrobes
