When deciding to buy dried hallucinogenic mushrooms, it is important to consider a few things. First, it is important to understand the legal implications and risks of buying and consuming these mushrooms. In some countries, psychedelic mushrooms are illegal and can lead to serious legal trouble. 

It is also important to consider the source of the dried magic mushrooms. It is best to purchase them from a reputable vendor who can provide information about the type of mushroom, its origin, and the potency of the mushroom. Purchasing mushrooms from a street vendor can be risky as the quality and safety of the mushrooms cannot be guaranteed.

It is also important to consider the experience level of the person ingesting the mushrooms. Those who are new to psychedelics should start with a low dose and increase the dose slowly to avoid any adverse reactions.

Lastly, it is important to consider the cost of the mushrooms. Dried mushrooms are more expensive than fresh mushrooms, and the cost can vary depending on the type, quantity, and potency. It is important to research the cost of the mushrooms before making a purchase to ensure that you are getting a fair price.

In conclusion, before buying dried hallucinogenic mushrooms, it is important to consider the legal implications and risks, the source of the mushrooms, the experience level of the person ingesting them, and the cost. Doing so will help ensure a safe and enjoyable experience.
