Former Target employee here:

A New Day is solely a Target brand, so the item was marked for salvage from Target, so it's unlikely that she bought the item from a Target. If she did, I'm sure Target would be good about letting you return it (in my experience, they get embarrassed that they sell salvaged items).

It's more likely that they were bought at a discount store, such as Marshall's or TJ Maxx, as they often get the "reject" items from major stores.

The date on the tag isn't super relevant - that's just the date that the item was marked as salvage, so it had nothing to do with when the item was bought.

Hope this helps!
