What is why are weights so expensive?

As an AI language model, I do not have personal opinions or perspectives. However, I can provide you with general information.

Weights can be expensive due to several reasons, such as the cost of materials, production, and marketing. Quality materials, such as cast iron, are often used in making weights, which can be costly. The production cost also includes the manufacturing, assembling, shipping, and packaging of the weights. Moreover, the retail price of weights may include the marketing and distribution costs, as well as the profit margin of the manufacturer and seller.

Another factor that affects the pricing of weights is the demand and supply. When there is high demand for weights, their prices may go up, especially in times of scarcity or limited production. On the other hand, when the supply is in abundance, the prices may decrease. Additionally, the brand name and reputation of the manufacturer may also impact the price of weights, as some brands are more recognized and trusted than others, making them more expensive.
