How to buy Crypto on Amazon?

Can you elaborate on the process of purchasing cryptocurrency on Amazon? As a consumer interested in diversifying my investment portfolio, I'm curious about the feasibility of this. Does Amazon actually allow for direct cryptocurrency purchases? If so, what are the steps involved? What payment methods are accepted? Are there any special considerations or limitations I should be aware of? I'd also like to know if there are any additional fees or commissions associated with this type of transaction. Clarifying these details would greatly assist me in making an informed decision.
