Heck, hope you don't mind if I throw mine in here too...I've actually got 4 to give away...got em all on the same day for posting my reviews...wish they would have spaced them out but I'm all about sharing the wealth. Cheers.
If the OP doesn't object I've got three codes (I think). One $10 off good until the 31st (had two, used one but can't remember which so I can send out both) and two $5 off good for another three weeks or so.
Good idea to offer them up so they don't go to waste.
