Have an agent pay from a funded balance

A commenter used Muse to finish a purchase after ordinary card checkout ran into bank verification trouble.

What they did
They asked Muse to handle the shopping task end to end. The first try went through the normal card route, but the bank’s 3-D Secure step stopped the unattended agent. After that, they used a pre-funded balance, and the agent completed the order by adding an $18 gift card against a $17.73 checkout.
How it went
The balance-based route finished without help, and the saved card was not charged at all. The main obstacles were checkout protections like 3-D Secure, login gates, and CAPTCHAs.
Tips
If you want an agent to buy something autonomously, fund the account ahead of time and leave room for small price differences. Even then, some stores may block the run before payment if they require extra verification or a login challenge.

I’ve placed [amount] into [account or balance name]. Search for [item] on [site/store] and choose the best option that can be paid for from that balance. If the exact total doesn’t line up, use a gift card or another allowed workaround to make the payment fit. Before you finalize anything, pause and show me the item, the final cost, the delivery details, and the payment method so I can approve it.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
