eg quality 25 would be 135+25=160
160+10%(16) = 176 then round up to 178 -180 depending on other offers.
however recently iv been able to sell for 200each, the other day i sold it all for 250 each.
just wondering where all the oil has gone and why the prices have risen? it doesnt bother me, in fact its good for me as i get more money
