If they set it up so it's a "preemptive return" of things that came from your wishlist to a predefined address they could likely work past the spirit if not the letter of the law.

I can envision an email that says "Aunt Milly is sending you a gift from your wishlist. Would you like to know what it is? Yes? It's that Gumby boxed set. Still want it? Ah, you bought it for yourself at Walmart. We'll make a note of that, you disloyal bastard. Ok, we'll just send you a gift card and a preaddressed envelope that you can use for that thank-you note you'll send to Auntie."

It's a money-saver for them; every return they have to deal with is a drain on the bottom line.
It's a win for the nephew; who needs two Gumby box sets?
Aunt Milly will never know.
