From the auction:
For every 1K under 25K on the final sales price will cause a delay in shipping by one week. Please do not bid if you have a problem with this!
Creative, but really?
I'm not sure you can actually do that and not violate EBAY ToS...
Yeah, really! ebay charges a fortune for "reserve". If they give me any problems then I say good by to ebay for good.
If you're willing to do that aren't you just as willing to screw over the buyer? You have already said several things that would keep me from ever buying it from you.
