Things id never buy online, mostly anything over 200+ and a bracket that falls within perfume,kayaks, jewellery, bikes, cars, fresh food, gifts, furniture.
In ten years on prediction, I think economics thus income and hours spent working v time, will have a lot to do with it. Its also sometimes cheaper to buy online because theres not many resources to cover it, its also quicker but only if you know what your buying.
In essence someone is always going to be less knowledgeable on certain trades and will most likely need assistance in their purchase if its means enough to them.
You’ will get others who don’t appear bothered about what they buy and will possibly make mistakes in their purchase and will therefore after a long period time want to seek advice or maybe try before you buy which would possible become favourable in the end. Ultimately I don’t think the retail industry will disappear completely in ten years.
