Credit Top-Up Cards

Every now and then, I see content I want to purchase on Marketplace. Unfortunately, even with the cashback I recevied from being an early-bird subscriber, many of this content is more expensive than the credit I currently have stored, and adding to it seems more complicated than it needs to be.

To solve this, what I propose is for a deal to be made with a major online retailer - Amazon, for example - where users can purchase top-up credit at different amounts. As with other credit options, these would consist of a digital code, which could then be redeemed through the website.
