Oops! Sent wrong item!

[billscountry716]

I sent the wrong item to a customer. I did not cancel the order. Instead, I printed out a new shipping label and sent the card again. Package intercept is more than the cost of the card. I've reached out to the buyer hoping they would send it back at my expense with an inconvenience fee. Maybe they will, maybe they won't. I was wondering if anyone else had devised a better way to handle this than the above-mentioned approach. Any help would be appreciated!
