Depends on how much it bothers you, and what kind of deal you got in the first place,
If the price was real good, and you love the uke otherwise, take the $25 and enjoy the uke.
If you paid top dollar, or if the uke doesn't really "speak" to you, send it back. Get a refund and start shopping again.
All a matter of perception....
Things get better with age. I'm approaching magnificent....
