One thought is that gift cards could have a one day delay before they can be spent. I'd imagine that 90% of gift cards are intended as presents anyway and thus would be unaffected, but the delay would still grant a cancellation window to scam cases like this.

Anecdotally I have a completely legitimate use case for that - apps like Fluz http://joinfluz.app.link/BETA and MileagePlusX kick back some dollars (or airline miles) for purchasing vendor gift cards through them.

Frequently as I am in the checkout line at Kohl's or Home Depot I'd buy a gift card for myself with the intent to wipe it out in the next few minutes at the checkout (Fluz, for one encourages that, and will send a notification whenever you're near a retailer that's in their network).
