Previously, our website had 1M silver and 1M iron ore products, which were relatively expensive for customers. We saw that our product packages were very diverse, such as grain+wood+iron ore+silver, or silver+iron ore packages. However, some customers find it difficult to calculate the price of silver for this package, thinking that a unit price of 1M silver is the true price. However, our package is actually very cost-effective, so we have launched many discounted packages, such as 1B Food+20M Silver=24 US dollars, which is equivalent to 1M=0.8 US dollars for silver.
