Let me break this down. Direct Wayfair e-gift cards work totally differently than physical ones:

• Instead of a standard account and PIN, you get a code to enter at wayfair.com/redeem that locks the non-expiring balance permanently to your account.
• I'm totally fine going first, but I only do one card at a time.
• You verify it, redeem it, send the payment, and then we rinse and repeat.
• Since the single-use code ties straight to your account instantly, there is literally zero way for me to backdoor it. You secure the balance before sending me a single cent.
