I do the bulk of my shopping online. I can only think of things like furniture that I want to see before I buy, and obviously that amounts to very occasional purchases.
I enjoyed shopping once, but can barely remember when. I agree that pedestrianisation has killed city centres. I worked in one, and loved the bustle, but last time I was there it was desolate by comparison. It's fine for the young and fit to nip about on e-bikes, or walk from one area to another, but for those of us with breathing problems, or who have mobility issues it's no joke. The buses stop outside the shopping areas and instead of seating areas on the streets there are flower arrangements. It feels as though councils want to deter shoppers.
Good public transport (maybe hop on/off trams going round the centre) is essential to getting people to make the effort to shop. I was a very early adopter of online shopping, and have had groceries delivered since the service became available, but would visit city centres if they were more accessible, and I don't count myself as disabled - more 'challenged'. I do enjoy a 'poosk' about when I'm on holiday though, looking at different shops in new places. I wonder if more 'mainstream' shopping will move online, and leave room for independent shops in town centres, with cities moving over to restaurants and places of entertainment?
