What would you think about people who are reselling by dozens atm if you were the CEO, or a worker of a well known high street shop which makes business by buying and selling second hand electronic products? Let's be serious, these people pay no taxes, at all. And to think anything else is to deceive yourself, or just trying to defend an illegit business for whatever the reason.
This well known shop has to buy a GPU from a customer, lets say a 3070. they are paying 816 pounds atm. I don't know if they make you prove that the GPU is actually yours, or you have to give them proof of purchase or whatsoever, but I think it wouldn't be rare if they had to charge for VAT again on this card really, how to prove VAT has already been paid? Then they will have to pay taxes, of course: Capital gains, corporation tax... whatever, you name it. You have a local, so you pay rent for it, and don't forget your employees, insurance... they are selling this card for 960£, so with a difference of 144£ in the buy-sell price, they are still making money. How much do you think they can actually make for each card? 25-50-75...100£? And don't forget they still have and do offer you warranty. Or that they are legally obliged to things like accept refunds the first days etc...
Do you think it is fair that people buy them for 700-750, or even 470£ for a FE, by abusing the system and no adhering to the rules retailers are imposing, just to sell them at 1100£? 630£ of benefit, nothing to pay, no obligations. Scalpers are doing unfair competitions even to retailers atm, and ******* the rest of us up on the way. That is my opinion at least, of course other people will have different ones... I am curious what you would think if someone decided to buy all the petrol from the petrol station and you had to decide between not buying petrol in 6 months at all, or having to pay 10 quid per litre... a free market, after all.
