Casual reminder that this is a scam:
Around the holidays this scam runs around a lot more because, obviously, people are buying things online. The goal of this scam is to get you to click on a sketchy link, or worse, get you to fill in personal information about yourself (here they're asking for you to give them your address; they might also ask for you to restate your credit card information just to "double check").
Don't do it. Don't click anything. It's a scam.
If you're worried it could be real, go to the website you bought the item from and log in there. If there's an issue with your shipping, it will be stated there.
Again: don't click on the link.
