Subscription

subscription, buy

Mnemonic

You lock your money inside a cage to save it. But a subscription reaches through the bars each month, snatching coins one by one. The cage can't protect your money—subscriptions always find a way through, draining you payment by payment.
Additional thoughts
Picture a birdcage stuffed with gold coins. A ghostly hand labeled 'auto-pay' slips between the bars every month, plucking coins out. The cage represents your failed attempt to guard your finances against recurring purchases.
Quick recall
Your money is locked in a cage, but a subscription reaches through the bars to snatch it monthly.
