I think very expensive things like solid gold game consoles, iPhones made from solid gold, and rare jewellery will be sold on online shopping websites for rich internet users, or the site will use the internet to tell the seller that you are interested in buying their expensive item rather than having the expensive item on display at a retail store where a robber can steal the item, the item gets damaged by shoppers, or the buyer gets robbed of his expensive item and money outside of the store which sells the expensive item.
The expensive item may not have a buyer in many years, or longer, so a retail store does not make money until it sells enough expensive items to pay the rent, electricity, and taxes.
