How do I Buy gift cards with Crypto?

Could you please elaborate on the process of purchasing gift cards with cryptocurrency? I'm curious to know the step-by-step procedure, including any specific platforms or services that facilitate such transactions. Is it a straightforward process, or are there any specific requirements or considerations I should be aware of? Additionally, are there any limitations or restrictions on the types of gift cards that can be purchased using crypto, and are there any fees or additional charges associated with these transactions? I'd appreciate any insight you could provide on this matter.
