A lot of the younger generation don't use cash. My oldest son is one. On holiday recently we had to pay his fair on the turntable ferry as they didn't accept card or phone payment.
Calmac are accepting card payment only due to covid.
Regarding the OP, I advertised some surplus power tools on FB recently at what I considered reasonable prices, some paid the asking price. Some bartered 🤔. One guy offered me £60 for a bench saw I advertised at £100, the nearly new TCT blade alone cost me £50!!!!
A Honda suitcase generator, working condition but needed a fuel tank repair, similar ones on fleabag at £200/£300, I asked for £50, guy phoned and said" if I pay now by transfer will you take £30? Can you guess the reply?😂
