Our prices run below the Grand Exchange and fluctuate to give customers the best deals we possibly can. We strive for excellence and give our customers a set price. Their price does not change if we deliver it and our prices have changed, we sell to them what they ordered the items at. Example: if I ordered 1k sharks at 600 ea, and when I got them they were 1k ea, I would be able to buy them at 600 each.
