Let's have some transparency.
shevaroller got his pharos (minus blood) from mrbrightside, who got his pharos (minus blood) from feroz, who got his pharos (minus blood) from sennax who sold his pharos blood to HiVoltage (for 20k).
mrbrightside: do you want me to deduct the shop price of pharos (90k) from you and give it to sheva, or will you buy it from market/deal finder at 10k (less than what the blood was sold for) and send it to sheva? Your end of the bargain is still yet to be upheld.
