Have to confess to putting my Amazon purchases through my credit card rather than Monzo. Partially to keep section 75 protection when appropriate, partially through inerita (easier to carry on with exisiting card than add Monzo). But.
If I were to use my Monzo account to pay for Amazon purchases directly, I’m pretty certain I would be adjusting the category as appropriate each and every time, if necessary. So only orders analagous to what I’d buy from the supermarket or similar would end up under shopping, while Blu-Rays and books would end up under Entertainment.
Looking at my last few orders, the picture it a little muddier (because Christmas and therefore gifts), but there’s a whole bunch of household goods (so, shopping), and only a few books (entertainment). My latest Amazon order rather screwed the pooch, though, by mixing household items and a couple of books in one order. Doh.
