That sucks. Sorry for the hassle. Is it still worth it for 10% off? If so, plead your case...tell them you had it and lost it or something similar. I would think they would want to sell you a bike and get the potential future business than to see you walk out the door.
Have you looked at the Tirenno's? They've only been on the market for a couple of months and although I'm not familiar with them personally, I am familiar with Colorado Cyclist's house brand - Douglas - and find them to be an excellent value.
I'll bet you my rear skewer the Tirenno's are made by a major manufacturer and re-badged - meaning they could be good. The component mix seems nice. They are on sale right now too and if you can order it online and get the discount, it may be worth checking out.
Also, post your request in the deals forum and see if somebody can get you a copy.
Keep pluggin'
