At $40, I would just keep it.

I have a related story. LL Bean has a lifetime, no questions asked warranty on everything they sell. Also, they mean it: you can return anything at any time for a full refund or replacement. Two years ago, my wife bought me a ~$300 GoreTex shell from them. The shell never fit right but I used it occasionally for one winter as I liked the color (!) and figured I could deal with it. Last winter I got fed up and brought the jacket back to see if they could do anything. I was immediately offered a full refund which I promptly plowed back into a sweet pair of boots. I felt kind of bad about this as it had been a full year but then I realized that LL Bean has earned my undying loyalty because of this service. It makes good business sense.
