[Owner] Improving logic with attracting more customers with higher newprice to rebuy_price ratio

[blackjack2693]

Interesting concept :) While I generally like the idea, shouldn't an owner consider the rebuy price compared to the price he bought it for instead of market prices? For example: I had an old GTX1060 lying around for a while. I sold it the moment the current rebuy prices became higher than what I paid for it when it was brand new :D
