Went to the new Target in Manhattan today and they had original Apple Watch Nylon Band in 42mm in Black for $14. Large discount from the original price of $49.99. I am on mobile, but can post a picture of the tag. Brickseek still also shows original price, so YMMV.
I'll also note that this Target in Manhattan isn't a "full" Target per say. It's more of a smaller sized down version that they have been rolling out in recent years. As a result, I do not think these stores show up on Brickseek. I would check around to see if there are these smaller Targets around and take a look if you have time.
Edit: Added picture of tag.
