Gifting Option in Marketplace

Hey everyone, I’m a bit confused why this isn’t already an option.

The whole way the subscription system is set up, it seems logical that players should be able to contribute by for example buying a book for the DM. Since the Master Tier is clearly designed for DMs (enabling shared content), it would make it easier to split costs. Wizard of the Coast benefits from the sale made and the financial burden doesn’t fall entirely on one person.

Or is the entire system designed, so the cost is supposed to only be on the DM?

Not to justify myself, my players asked me, if they could gift me a book, and when i looked it up, i realized it isn't even possible. With a focus on online play, please make gifting possible. 

It is an option, when you go to check out there’s a tick box labelled “buy as gift” which then produces a download card for the recipient to redeem
