undefinedI ordered this Hape - Happy Hour Clock - Time Learning Puzzle from the Amazon Warehouse. It arrived with a small tear in the packaging and the "8" was missing... Oh no! 

Amazon offered a full refund if I shipped it back, but I didn't want to send the whole thing back just for one missing piece. I emailed Hape and they replied within a a couple hours:

Thank you for contacting Hape. We are more than happy to send you the missing 8 to complete your toy. My apologies that it came missing.

If you could please provide your full name mailing address and the best phone number to reach you at if need be.

Thank you and we look forward to hearing back from you soon.

Awesome!  The piece arrived two days later.  

So before you give up on the item, make sure to contact the manufacturer.  A lot of the time, they're happy to make things right!
